Density=2g/mL and volume=20mL what is mass
Answer:
40g
Explanation:
Mass = density x volume
= 2 x 20
= 40g
Answer:
m = V × ρ
= 20 milliliter × 2 gram/cubic meter
= 2.0E-5 cubic meter × 2 gram/cubic meter
= 4.0E-5 gram
= 4.0E-8 kilogram
Explanation:
The density of a material, typically denoted using the Greek symbol ρ, is defined as its mass per unit volume.
ρ =
m
V
where:
ρ is the density
m is the mass
V is the volume
The calculation of density is quite straightforward. However, it is important to pay special attention to the units used for density calculations. There are many different ways to express density, and not using or converting into the proper units will result in an incorrect value. It is useful to carefully write out whatever values are being worked with, including units, and perform dimensional analysis to ensure that the final result has units of mass volume. Note that density is also affected by pressure and temperature.

Each of the eight planets in the Solar System follows a different elliptical orbit around the Sun. An ellipse is a type of oval shape. Each planet's orbit is at a different distance from the Sun than the other planets' orbits.
Beginning nearest to the Sun, the order of the planets is: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
Based on this order, which of the following is true of Mercury?
A.
It must travel farther than Earth does to complete one orbit around the Sun.
B.
It travels a shorter distance than Earth does to complete one orbit around the Sun.
C.
It travels the same distance as Earth does to complete one orbit around the Sun.
D.
It must travel in the opposite direction around the Sun than Earth does.
Answer:
It must travel farther than Earth does to complete one orbit around the Sun.
Explanation:
Each planet orbits around the Sun along an elliptical path. The farther away from the Sun a planet is, the larger the ellipse. The larger the ellipse, the longer the distance around it. Because the orbit of Mars is larger than the orbit of Earth, Mars must travel farther than Earth does to complete one orbit around the Sun.
Mercury travels a shorter distance than Earth does to complete one orbit around the Sun.
Based on the positions of the 8 planets from the sun, Mercury is closest to the sun. The implies that the distance of Mercury from sun is very short when compared to Earth or other planets.
The shorter the distance, the shorter time it would require to make a complete orbit around the sun.
For instance;
It takes Mercury about 88 days to make a complete orbit around the sunIt takes Earth about 365 days to make a complete orbit around the sunThus, we can conclude that Mercury travels a shorter distance than Earth does to complete one orbit around the Sun.

Latent heat of vaporization refers to which changes of state?
a. liquid to gas or gas to liquid
b. solid to gas or gas to solid
c. solid to liquid or gas to liquid
d. gas to liquid or liquid to solid
Answer:
I think it is A and yes I think it is A but I think it is A and I am not playing with you
Latent heat of vaporization refers to changes of state from liquid to gas or gas to liquid. Hence, option (a) is correct.
What is latent heat?In thermodynamics, latent heat is the heat or energy that is absorbed or released when a substance undergoes a phase change. A liquid to solid transition or a gas to liquid transition are both possible. Enthalpy, another heat attribute, is connected to latent heat.
When matter breaks down and transitions from a fluid to a gas at a constant temperature, this is known as latent heat of vaporization.
The heat of water vaporization is the highest known temperature. The heat of vaporization is defined as the amount of heat necessary to turn 1 g of a fluid into a fume without causing the fluid's temperature to change.

A car increase velocity from 30 m/s to 60 m/s in 4 seconds
Answer:
Acceleration = 7.5
Explanation:
Vf = 60m/s
Vi = 30m/s

If you are driving forward and suddenly break, what would happen to your body and which law does that demonstrate?
A. Move forward, 1st Law
B. Go back, 2nd Law
C. Go back, 1st Law
D. Move forward, 2nd Law
Answer:
1st law you would move forward if you were sitting right with a seatbelt
If you are driving forward and suddenly break due to inertia your body moves forward demonstrating newton's first law of motion. Therefore, option (A) is correct.
What Is Newton’s First Law of Motion?Newton’s 1st law of motion can be defined as the object will stay in the state of rest or uniform motion in a straight line until and unless an external force acts on it.
Once the body starts to move, it won't stop or change its speed until and unless some external force applies upon it one or more times. Newton's 1st law of motion is also known as law of inertia.
There are two conditions for Newton's first law of motion. If an object is at rest, velocity (v) and acceleration (a) are equal to zero. Therefore, the object will continue to be at rest state.
When a body is already in motion, velocity will be non-zero (v ≠ 0), while acceleration (a = 0) is equal to zero. Therefore, the body will continue to be in motion with the same speed and in the same direction.

Why does fulcrum placement matter for how a lever works?
Answer:
The mechanical advantage of using a lever is affected by the distance between the effort and the fulcrum and by the placement of the load. ... When the fulcrum is centered between the load and the lift, the amount of effort exerted to push down on the lever equals the amount of the load being lifted on the other end.

A racecar is traveling at a speed of 80.0 m/s on a circular
racetrack of radius 450 m. What is the centripetal force on the
racecar if its mass is 500 kg?
The centripetal force on the race car if its mass is 500 kg is 7,111.1N
The formula for calculating the centripetal force of the car is expressed as
[tex]C=\frac{mv^2}{r}[/tex]
m is the mass of the car
v is the velocity of the car
r is the radius of the circular path
Given the following parameters
m = 500kg
v = 80.0m/s
r = 450m
Substitute the given parameters into the formula as shown
[tex]F_c=\frac{500 \times 80^2}{450}\\F_c=\frac{500\times 6400}{450}\\ F_c=\frac{3,200,000}{450}\\F_c= 7,111.1N[/tex]

2. James drives 400 km in 5 hours to his grandmothers. What is the distance he will travel?
3. James drives 400 km in 5 hours to his grandmothers. What is the time it takes to get there?
Answer:
See the answer below
Explanation:
1. Speed is calculated as the ratio of distance and time. Hence, Jame's speed can be calculated as:
400/5 km/hr = 80 km/hr
The unit for the speed would be km/hr. This can also be converted to m/s:
80 km = 80,000 m
1 hr = 3,600 s
80 km/hr = 80,000/3600 m/s = 22.22 m/s
2. Since James drove 400 km in 5 hours, the distance he drove is 400 km.
3. The time it took for James to get there is 5 hours.

An apple is dropped from rest. A. Calculate the vertical velocity of the apple at 2.5 seconds? B. Calculate how far the apple has fallen in 2.5 seconds?
Answer:
A. 24.5 m/s
B. 30.63 m
Explanation:
A. Determination of the vertical velocity of the apple.
Initial velocity (u) =?
Time (t) = 2.5 s
Acceleration due to gravity (g) = 9.8 m/s²
Vertical velocity (v) =?
v = u + gt
v = 0 + (9.8 × 2.5)
v = 0 + 24.5
v = 24.5 m/s
Thus, the vertical velocity of the apple is 24.5 m/s.
B. Determination of how far the apple has fallen.
Time (t) = 2.5 s
Acceleration due to gravity (g) = 9.8 m/s²
Height (h) =.?
h = ½gt²
h = ½ × 9.8 × 2.5²
h = 4.9 × 6.25
h = 30.63 m
Thus, the apple has fallen 30.63 m in 2.5 s.
A 1200 kg car is traveling 21.1 m/s. It collides with a stationary car of mass 1500 kg, and the two vehicles lock together. What is the speed of the combined cars immediately after the collision?
A) 7.5 m/s
B) 16.5 m/s
C) 9.4 m/s
D) 11.8 m/s
Answer:
C) 9.4 m/s
Explanation:
[tex]m_1[/tex] = Mass of moving car = 1200 kg
[tex]u_1[/tex] = Initial velocity of moving car = 21.1 m/s
[tex]m_2[/tex] = Mass of stationary car = 1500 kg
[tex]u_2[/tex] = Initial velocity of stationary car = 0
v = Velocity of the combined cars
As the momentum in the system is conserved we have
[tex]m_1u_1+m_2u_2=(m_1+m_2)v\\\Rightarrow v=\dfrac{m_1u_1+m_2u_2}{m_1+m_2}\\\Rightarrow v=\dfrac{1200\times 21.1+1500\times0}{1200+1500}\\\Rightarrow v=9.378\approx 9.4\ \text{m/s}[/tex]
The velocity of the combined mass is 9.4 m/s.
