Answer:
the answer is c
Explanation:
because if the force of gravity increases its not gonna change its weight it will just float
Answer:
B
Explanation:
Weight is the amount of force gravity is exerting on something, so if gravity's force increases, weight would increase as well

Ohnny walks 900 meters to the store to buy a candy bar. He then walks back home. His total trip took him 30 minutes. What was his average speed? 0 points 1 m/s 10 m/s 30 m/s 27,000 m/s
Answer:
Average speed = 1 m/s
Explanation:
Given that,
Ohnny walks 900 meters to the store to buy a candy bar. He then walks back home. It would mean that the total distance covered by him is 900 m + 900 m = 1800 m
His total trip took him 30 minutes or 1800 seconds
We need to find the average speed. It is equal to the total distance divided by the total time taken. So,
[tex]v=\dfrac{1800\ m}{1800\ s}\\\\v=1\ m/s[/tex]
So, his average speed is 1 m/s.
Please help me with thus question (picture) D:
well thanks for the Information
Explanation:
Torque = Force * Perpendicular distance of the force = 10N * 0.8m = 8Nm.
In diagram A, both torques are acting in a clockwise direction. Hence the net torque is 2N * 1m + 4N * 1m = 6Nm, clockwise.
In diagram B, the torques are acting in opposite directions. For the clockwise one, its torque is 5N * 4m = 20Nm. For the anticlockwise one, its torque is 2N * 10m = 20Nm. Since they are in opposite directions and are equal, they cancel out each other.
Hence net force = 0N and net torque = 0Nm.

(Choice C) C It has a nucleus.
(Choice D) D It is single-celled.
Answer:
it has nucleus
Explanation:
Giardia is a microscopic single celled prokaryotic organism that causes giardiasis. Giardiasis is an intestinal Infection in humans and dogs which is caused by giardia. It is an eukaryotic organism that have nucleus and nuclear membrane but it lacks other ORGANELLES that are present in Eukaryotic organisms. It causes diarrhoea in humans and woman's can get infected from dogs.

The answer is nucleus.
Prokaryotes dont have a nucleus, but this Giardia is a eukaryotic organism so it has a nucleus.
Explanation:
A person walks first at a constant speed of 4.90 m/s along a straight line from point A to point B and then back along the line from B to A at a constant speed of 3.05 m/s.A) What is her average speed over the entire trip?
B) What is her average velocity over the entire trip?
Answer:
A.) 3.975 m/s
B.) 0.925 m/s
Explanation:
Given that a person walks first at a constant speed of 4.90 m/s along a straight line from point A to point B and then back along the line from B to A at a constant speed of 3.05 m/s.
A) What is her average speed over the entire trip?
The average speed = (4.90 + 3.05)/2
Average speed = 7.95/2
Average speed = 3.975 m/s
B) What is her average velocity over the entire trip?
Since velocity is a vector quantity, that is, we consider both the magnitude and direction
Average velocity = ( 4.90 - 3.05)/2
Average velocity = 1.85/2
Average velocity = 0.925 m/s

If a skateboarder is moving at 4 meters per second then changes its velocity to 10
meters per second over the course of 10 seconds what is the skateboards acceleration?
Answer:
i was doing this is it actually 0.6
Explanation:
;D
The acceleration of the skateboard from its initial velocity to the final velocity over the given time is 0.6m/s².
What is Motion?Motion is simply the change in position of an object over time.
From the First Equation of Motion;
v = u + at
Where v is final velocity, u is initial velocity, a is acceleration and t is time elapsed.
Given the data in the question;
Initial velocity u = 4m/sFinal velocity v = 10m/sTime elapsed t = 10sAcceleration of the skateboard a = ?To determine the acceleration of the skateboard, we substitute our given values into the expression above.
v = u + at
10m/s = 4m/s + ( a × 10s)
( a × 10s) = 10m/s - 4m/s
a × 10s = 6m/s
a = 6m/s ÷ 10s
a = 0.6m/s²
Therefore, the acceleration of the skateboard from its initial velocity to the final velocity over the given time is 0.6m/s².

A boat sailed 560 km in 8 hrs. It took three hours to travel the first 150 km. What was it’s average speed for the remaining journey?
Answer:
82 km/h
Explanation:
Given that A boat sailed 560 km in 8 hrs. It took three hours to travel the first 150 km. That is,
The remaining distance will be:
560 - 150 = 410 km
the remaining time will be:
8 - 3 = 5 hours
For the remaining Journey, average speed will be:
Speed = distance/time
Speed = 410/5
Speed = 82 km/h
Therefore, the average speed for the remaining journey will be 82 km/h

In Europe, gas cost approximately €0.98 per liter. How many dollars($) per gallon is this? using a factor method
Answer:
€0.98 per liter = 4.377 doller per gallon
Explanation:
It is given that, In Europe, gas cost approximately €0.98 per liter. We need to convert it into dollars($) per gallon.
We know that, 1 euro = 1.18 United States Dollar
1 litre = 0.264172 US gallon
Cost of gas in Europe is €0.98 per liter.
[tex]0.98\ \text{euro/ liter}=\dfrac{0.98\times 1.18\ \text{doller}}{0.264172\ \text{gallon}}\\\\=4.377\ \text{doller/gallon}[/tex]

The news media, such as newspapers and television stations, carry current events worldwide. Explain how the way news travels is similar to the way a wave travels.
Answer:
A simile can be established with the news, where the fact that occurs is the matter of has some type of oscillation or disturbance, which occurs somewhere and is there, the news is the wave that carries the information of this fact the energy of the same to all points, therefore it is equivalent to a traveling wave.
Explanation:
Traveling waves are disturbances of the medium that are transmitted with a constant speed, where matter is subjected to oscillations around its equilibrium point, transporting only energy.
A simile can be established with the news, where the fact that occurs is the matter of has some type of oscillation or disturbance, which occurs somewhere and is there, the news is the wave that carries the information of this fact the energy of the same to all points, therefore it is equivalent to a traveling wave.
The news is the wave that carries the information of this fact and the energy of the same to all points, making it equivalent to a traveling wave.
What is a wave?A wave is a phenomenon that flows across a material medium without leaving any lasting mark. Mechanical or electromagnetic waves can be used to classify them.
Transverse and longitudinal are the two main forms.
The wave can be compared in the form of news as
The news is the wave that carries the information of this fact and the energy of the same to all points, making it equivalent to traveling. wave.
Traveling waves are medium disturbances that are conveyed at a constant pace, where matter oscillates around its equilibrium point, transferring only energy.
A parallel may be drawn with the news, where the fact that occurs is the issue of having some sort of oscillation or disturbance.
Hence the news is compared with the help by the help of energy and information.

Hence , this is the required solution .
a man pulls a box with a force of 90.0 N directed along the handle which makes angle of 45 degrees with the ground. find the horizontal and vertical components of this force
Answer:
The horizontal component of the force, Fₓ = 63.64 N
The vertical component of the force, [tex]F_y[/tex] = 63.64 N
Explanation:
Given;
magnitude of the force, F = 90 N
angle between the handle and the ground, θ = 45°
The horizontal component of the force, Fₓ = Fcosθ
Fₓ = 90 x cos45
Fₓ = 63.64 N
The vertical component of the force, [tex]F_y = Fsin \theta[/tex]
[tex]F_y[/tex] = 90 sin45
[tex]F_y[/tex] = 63.64 N
Therefore, the horizontal and vertical components of the force is 63.64 N.
