Answer:
2 m/s²
Explanation:
If changes speed by 2 meters per second each second means:
2 m/s²
Because it changes constantly it veloctity.
Remember the aceleration changes the velocity.
Answer:

Explanation:
Given
e=100 N/C
M=0.15 g

The ratio of the electric force on the bee to the bee's weight can be determined by the following formula



A baseball would hit the bat harder. This is because the baseball is a lot heavier and more dense than the plastic ball. The keyword that you're looking for is density. The baseball is dense.
Incomplete question as number of moles and length is missing.So I have assumed 3 moles and length of 0.300 m.So the complete question is here:
Three moles of an ideal gas are in a rigid cubical box with sides of length 0.300 m.What is the force that the gas exerts on each of the six sides of the box when the gas temperature is 20.0∘C?
Answer:
The Force act on each side is 2.43×10⁴N
Explanation:
Given data
n=3 mol
L=0.3 m
Temperature=20.0°C=293 K
To find
Force F
Solution
To get force act on each side it would employ by
F=P.A
Where P is pressure
A is Area
First we need to find pressure by applying ideal gas law
So

So The Force is given as:

The Force act on each side is 2.43×10⁴N
Answer:
he covered 80km his displacement was 20km
Explanation:
displacement is the distance from the starting point so in this case its 20 (50-30) and total distance covered is how many kilometers he drove in total
