Answer:
Increase in temperature
Increase in pressure
Explanation:
For the rate of collisions to increase, It can happen in various ways
1. The gasses can be made to move faster: This can be done by increasing their temperature. An increase in the temperature of the gases directly relates to a corresponding increase in their kinetic energy. This means that the molecules of the gases can move with a greater velocity, which will increase collision rates.
2. The volume of the container can be reduced: Consider this; If the container is made smaller, the molecules of the gases will have less space to move about. This means that they will be bumping into the walls of the container more frequently. This reduction in volume leads to an increase in the pressure of the gas. This is exactly what happens in a piston-cylinder assembly
The increase in the rate of collisions between gas molecules in a container should result in Increase in temperature and Increase in pressure
Reasons for increasing the rate of collisions:1. In the case when the gasses should be quick faster, due to this, the temperature should be increased. In this, the gases molecules should be moved have high velocity
2, Here the container volume should be decreased. Due to this, the volume should be decreased that results in the increment of the gas pressure.
Therefore, The increase in the rate of collisions between gas molecules in a container should result in Increase in temperature and Increase in pressure

A rock is thrown straight upward with an initial velocity of 20 m/s where the downward acceleration due to gravity is -10 m/s^2. How long is the ball in the air before it returns to the thrower's hand?
Answer:
4 seconds
Explanation:
Given:
Δy = 0 m
v₀ = 20 m/s
a = -10 m/s²
Find: t
Δy = v₀ t + ½ at²
0 m = (20 m/s) t + ½ (-10 m/s²) t²
0 = 20t − 5t²

There are 100 simple pendulums in a room having identical bobs which are displaced to different extents but only 25 of these pendulums have different time periods. What do you think would be the reason?
Explanation:
The time period of a simple pendulum is given by :
[tex]T=2\pi \sqrt{\dfrac{L}{g}}[/tex]
L is length of the pendulum and g is acceleration due to gravity
It is very much clear that the time period depends on the length of the pendulum.
In this problem, there are 100 simple pendulums in a room having identical bobs which are displaced to different extents but only 25 of these pendulums have different time periods. The only reason for 25 pendulums having different time periods is that they have different lengths than the other 75 pendulums.

Explanation:
A cliff diver from the top of a 100 (m) cliff. He begins his dive by jumping up with a velocity of 5 (m/s) a. How
long does it take for him to hit the water below? b. What is his velocity right before he hits the water?
Answer:
A.) 4.81 seconds
B.) 44.6 m/s
Explanation:
He begins his dive by jumping up with a velocity of 5 (m/s).
Let us first calculate the maximum height reached by using third equation of motion
V^2 = U^2 - 2gH
At maximum height, V = 0
0 = 5^5 - 2 × 9.8H
19.6H = 25
H = 25 /19.6
H = 1.28 m
The time taken for the diver to reach the water from the maximum height can be calculated by using second equation of motion.
Where height h = 1.28 + 100 = 101.28 m
h = Ut + 1/2gt^2
As the diver drop from maximum height, U = 0
101.28 = 1/2 × 9.8 × t^2
4.9t^2 = 101.28
t^2 = 101.28/4.9
t^2 = 20.669
t = sqrt ( 20.669)
t = 4.55s
As the diver jumped up, the time taken to reach the maximum height will be
Time = 1.28 / 5 = 0.256
The time taken for him to hit the water below will be 0.256 + 4.55 = 4.81 seconds
B.) Velocity right before he hits the water will be
V^2 = U^2 + 2gH
But U = 0
V^2 = 2 × 9.8 × 101.28
V^2 = 1985.09
V = 44.6 m/s
A.) The time taken should be 4.81 seconds
B.) The velocity should be 44.6 m/s
Calculation of the time taken and velocity:Here we used third equation of motion
V^2 = U^2 - 2gH
At maximum height, V = 0
Now
0 = 5^5 - 2 × 9.8H
19.6H = 25
H = 25 /19.6
H = 1.28 m
Here the second equation of motion.
Here height h = 1.28 + 100 = 101.28 m
So,
h = Ut + 1/2gt^2
Since the diver drop from maximum height, U = 0
So,
101.28 = 1/2 × 9.8 × t^2
4.9t^2 = 101.28
t^2 = 101.28/4.9
t^2 = 20.669
t = sqrt ( 20.669)
t = 4.55s
Now
Time = 1.28 / 5 = 0.256
Finally the time should be
= 0.256 + 4.55
= 4.81 seconds
B.)
We know that
V^2 = U^2 + 2gH
But U = 0
So,
V^2 = 2 × 9.8 × 101.28
V^2 = 1985.09
V = 44.6 m/s

A car starts to move from rest after 5 seconds its velocity becomes 15m/s, find the acceleration of the car.
Answer:
acceleration of the car is 3 m\s^2
Explanation:
from rest means the initial velocity (vi) is zero
time = 5s
final velocity (vf) = 15m\s
a = vf - vi \ t
a = (15-0) \ 5
a= 3 m\s^2
which means that the car is speeding up 3 meters every second
Answer:
3m/s
Simple
Explanation:
Solution,
U=0
Velocity=15m/s
Time=5 sec
Now,
Acceleration=V-U÷T
=15m/s-0÷5
=15m/s÷5
=3m/s

Maria walks 20 ft north, 35 ft east, and 20 ft south to get to the pool. Find her distance and displacement.
Answer: distance = 75ft
displacement = 35ft east
The required displacement of maria to get to the pool is 35 ft and the distance is 75 ft.
What are distance and displacement?To solve this problem, we first need to understand the difference between distance and displacement.
Distance is the total length traveled by an object, regardless of its starting and ending points. In this case, the distance traveled by Maria would be the sum of the distances of each segment of her journey,
Distance = 20 ft + 35 ft + 20 ft = 75 ft
Displacement, on the other hand, is the straight-line distance from the starting point to the ending point, measured in a straight line.
So let's assume the movement of maria on coordinate where North and East are positive movements and West and south are negative now add the distances,
Displacement =20 + 35 - 20 = 35 ft
Thus, the required displacement of maria to get to the pool is 35 ft and the distance is 75 ft.
