Answer:
the constant force applied by Kitty is 8 N.
Explanation:
Given;
work done by Kitty, W = 32 J
distance moved by Kitty's trolley, d = 4 m
Let the constant force applied by Kitty = F
The work done by Kitty is calculated as follows;
W = F x d
F = W / d
F = 32 / 4
F = 8 N.
Therefore, the constant force applied by Kitty is 8 N.
Answer:
The cloud moves 9050 meters to the east in 12.5 minutes.
Explanation:
Let suppose that mass of the cloud is negligible. meaning that effects of gravity are negligible and that altitude of the cloud remains constant. If the cloud drifts at constant velocity, travelled distance is defined by following formula:
(1)
Where:
- Velocity, in meters per second.
- Time, in seconds.
If we know that and , then the travelled distance after 12.5 minutes is:
The cloud moves 9050 meters to the east in 12.5 minutes.
<span>To know if there were other factors that affected the volume of a gas, Genaris and her classmates should: </span>"formulate a new hypothesis with the same dependent variable but a different independent variable as the original hypothesis." In this case, the dependent variable is the volume of the gas and the new independent variable is a factor they think will affect the volume of the gas.
Answer:
zero
Explanation:
If the car is moving at a constant velocity then there cannot be any acceleration. Acceleration is any change in velocity over time. If velocity doesn't change, then there is no acceleration.
The webbing on a duck's foot creates a larger surface area, which means the force of its weight is distributed over more surface area and therefore there is less pressure on the mud and its not likely to be displaced as much, so the foot doesn't get stuck.
