A company is creating a new mosquito repellent, and needs to figure out how much is needed to stop mosquito bites. They find volunteers from the nearby college. Each person is given either 1mL, 2mL, or 3mL of the repellent to rub on their arm. Some volunteers are given no repellent. Each person is then put in a room with mosquitoes for 10 minutes. Numbers of bites are measured for each volunteer.
In Experiment 1 above, what is the independent variable?
The independent variable is the different amount of repellent each person is given. This is because it does not depend on any variable. The dependent variable is what they are measuring, which would be the number of bites on each volunteer.

a force of 5.0 n is applied to a point object at 30o with the horizontal. another force of 10.0 n is applied at 120o . a) determine the net force (the magnitude and angle)
The net force calculated is 5 N. The total of all forces exerted on an object is known as the net force. A mass can accelerate due to net force. A body is subject to another force whether it is at rest or in motion.
The combined effect (the sum) of all pushing and pulling forces that are really operating on an object is known as the net force. An object will accelerate in the direction of the net force if the pushing and pulling forces acting on it are not equal (a net force acts).When there are a lot of forces acting on a system, the term "net force" is employed.
We now have a 30° - 60° /90° right triangle because this force does produce a 30° angle with the y-axis.

Answer:when a certain amount of violet light and yellow light shine on a metal surface only violet light produces an electric current describe how an increase in the intensity of each type of light will affect the amount of current produced, how does quantization help to explain these observations? Question thumb_up 100%
Explanation:
An increase in the intensity of violet light will lead to a proportional increase in the amount of electric current produced, as more violet photons will have enough energy to liberate electrons through the photoelectric effect.
However, an increase in the intensity of yellow light will not affect the electric current, as even with higher intensity, yellow photons do not possess sufficient energy to release electrons from the metal surface. This observation can be explained by quantization, which states that light energy is quantized into discrete packets called photons.
Each photon must possess a minimum energy threshold (the work function) to cause electron emission. Violet light photons have higher energy and can overcome the work function, while yellow light photons do not have enough energy and thus cannot produce a current, regardless of their intensity.

a. How far it goes
b. How high it goes
c. How long it's in the air
d. Its final velocity
Answer:
Range of the projectile: approximately [tex]1.06 \times 10^{3}\; {\rm m}[/tex].
Maximum height of the projectile: approximately [tex]80\; {\rm m}[/tex] (approximately [tex]45.0\; {\rm m}[/tex] above the top of the cliff.)
The projectile was in the air for approximately [tex]7.07\; {\rm s}[/tex].
The speed of the projectile would be approximately [tex]155\; {\rm m \cdot s^{-1}}[/tex] right before landing.
(Assumptions: drag is negligible, and that [tex]g = 9.81\; {\rm m\cdot s^{-1}}[/tex].)
Explanation:
If drag is negligible, the vertical acceleration of this projectile will be constantly [tex]a_{y} = (-g) = (-9.81)\; {\rm m\cdot s^{-2}}[/tex]. The SUVAT equations will apply.
Let [tex]\theta[/tex] denote the initial angle of elevation of this projectile.
Initial velocity of the projectile:
vertical component: [tex]u_{y} = u\, \sin(\theta) = 153\, \sin(11.2^{\circ}) \approx 29.71786\; {\rm m\cdot s^{-1}}[/tex]horizontal component: [tex]u_{x} = u\, \cos(\theta) = 153\, \cos(11.2^{\circ}) \approx 150.086\; {\rm m\cdot s^{-1}}[/tex].Final vertical displacement of the projectile: [tex]x_{y} = (-35)\; {\rm m}[/tex] (the projectile landed [tex]35\: {\rm m}[/tex] below the top of the cliff.)
Apply the SUVAT equation [tex]v^{2} - u^{2} = 2\, a\, x[/tex] to find the final vertical velocity [tex]v_{y}[/tex] of this projectile:
[tex]{v_{y}}^{2} - {u_{y}}^{2} = 2\, a_{y}\, x_{y}[/tex].
[tex]\begin{aligned} v_{y} &= -\sqrt{{u_{y}}^{2} + 2\, a_{y} \, x_{y}} \\ &= -\sqrt{(29.71786)^{2} + 2\, (-9.81)\, (-35)} \\ &\approx (-39.621)\; {\rm m\cdot s^{-1}}\end{aligned}[/tex].
(Negative since the projectile will be travelling downward towards the ground.)
Since drag is negligible, the horizontal velocity of this projectile will be a constant value. Thus, the final horizontal velocity of this projectile will be equal to the initial horizontal velocity: [tex]v_{x} = u_{x}[/tex].
The overall final velocity of this projectile will be:
[tex]\begin{aligned}v &= \sqrt{(v_{x})^{2} + (v_{y})^{2}} \\ &= \sqrt{(150.086)^{2} + (-39.621)^{2}} \\ &\approx 155\; {\rm m\cdot s^{-1}} \end{aligned}[/tex].
Change in the vertical component of the velocity of this projectile:
[tex]\begin{aligned} \Delta v_{y} &= v_{y} - u_{y} \\ &\approx (-39.621) - 29.71786 \\ &\approx 69.3386 \end{aligned}[/tex].
Divide the change in velocity by acceleration (rate of change in velocity) to find the time required to achieve such change:
[tex]\begin{aligned}t &= \frac{\Delta v_{y}}{a_{y}} \\ &\approx \frac{69.3386}{(-9.81)} \\ &\approx 7.0682\; {\rm s}\end{aligned}[/tex].
Hence, the projectile would be in the air for approximately [tex]7.07\; {\rm s}[/tex].
Also the horizontal velocity of this projectile is [tex]u_{x} \approx 150.086\; {\rm m\cdot s^{-1}}[/tex] throughout the flight, the range of this projectile will be:
[tex]\begin{aligned}x_{x} &= u_{x}\, t \\ &\approx (150.086)\, (7.0682) \\ &\approx 1.06 \times 10^{3}\; {\rm m} \end{aligned}[/tex].
When this projectile is at maximum height, its vertical velocity will be [tex]0[/tex]. Apply the SUVAT equation [tex]v^{2} - u^{2} = 2\, a\, x[/tex] to find the maximum height of the projectile (relative to the top of the [tex]35\; {\rm m}[/tex] cliff.)
[tex]\begin{aligned}x &= \frac{{v_{y}}^{2} - {u_{y}}^{2}}{2\, a} \\ &\approx \frac{0^{2} - 29.71786^{2}}{2\, (-9.81)} \\ &\approx 45.0\; {\rm m}\end{aligned}[/tex].
Thus, the maximum height of the projectile relative to the ground will be approximately [tex]45.0\; {\rm m} + 35\; {\rm m} = 80\; {\rm m}[/tex].
You are on a hike in the mountains. You have 3.23 km left to go before your next camp-site. The sun will set in 5.34 h.
What average speed must you walk to get to camp at sunset
Average speed corresponds to the total distance traveled in a specific time interval. Given distance and time information just divide it.
Average speed = 3.23KM/5.34h = 0.604km/h
Hence, you should not have a speed of less than 0.604km/h if you want to catch the sunset.
Average speed is calculated by dividing the total distance something has traveled by the total time it took to travel that distance. Velocity is how fast something is going at a given moment. Average speed measures the average speed while moving. Average speed is calculated by dividing the total distance traveled by the time interval. For example, the average speed of a person who takes him 40 minutes to travel 20 miles north and then 20 miles south (to reach the same place) is 40 miles divided by his 40 minutes.

Tarzan (m = 80 kg) is on a quest to save Jane. He runs towards a rope with a velocity of 12 m·s-1 . He grabs onto the rope. To what height will Tarzan swing?
The height to which Tarzan swings with a mass 80 kg and a velocity of 12 m / s is 7.2 m
K = 1 / 2 m v²
U = m g h
E = K + U
E = Total mechanical energy
K = Kinetic energy
U = Potential energy
m = Mass
g = Acceleration due to gravity
h = Vertical height
v = Velocity
Since Tarzan swings, it represents half the motion of pendulum. Therefore total mechanical energy is constant.
[tex]E_{i}[/tex] = [tex]E_{f}[/tex]
m = 80 kg
[tex]v_{i}[/tex] = 12 m / s
[tex]v_{f}[/tex] = 0
[tex]h_{i}[/tex] = 0
g = 10 m / s²
According to Law of conservation of Energy,
[tex]K_{i}[/tex] + [tex]U_{i}[/tex] = [tex]K_{f}[/tex] + [tex]U_{f}[/tex]
( 1 / 2 * m * [tex]v_{i}[/tex]² ) + ( m g [tex]h_{i}[/tex] ) = ( 1 / 2 * m * [tex]v_{f}[/tex]² ) + ( m g [tex]h_{f}[/tex] )
( 1 / 2 * 80 * 12² ) + 0 = 0 + ( 80 * 10 * [tex]h_{f}[/tex] )
[tex]h_{f}[/tex] = 5760 / 800
[tex]h_{f}[/tex] = 7.2 m
Therefore, Tarzan will swing to a height of 7.2 m

If you apply a force of 10 N to a box and push it 10 min 10 s. how much power didyou deliver?
10 watt power will be delivered to push the box for 10 min 10 seconds by applying force of 10N to a box .
What is power and how much is delivered to push the box for 10 minutes 10 second?Power is the energy we exert per unit time. Also power is the product of voltage supply and current.Though power have lots of definitions in its own way , here we talk about the power which is the work unit time.Given is the force which is 10 N and the time that is 10 min 10 second .Now applying the formula P= work/time , that is 100Nm/10s = 10 watt.Work have been calculated as the product of force and displacement = 10N X10m =100Nm.To know more about power visit:

What is a Straight Line Motion?If an object's location changes over time in respect to its surroundings, it is said to be in motion. An object's position changes over time. There is just one kind of motion, and that is linear motion.
Immediately Speed and Immediately Velocity:Immediately Speed. Instantaneous speed is the velocity of an item at a certain instant in time.
A particle's instantaneous velocity is its speed at any given moment in time or location along its route.
Final velocity: 0 m/s
Initially moving at 15 m/s
Acceleration equals 2 m/s^2.
Arrange to address the time problem:
t = 5 seconds
Use the following to calculate an distance at a constant rate:
Distance is equal to ( Vf +Vo)/ Time
Distance: (0 + 15 m/s)/ 5 sec
