What is the momentum of A 200 kg shark swimming at 15 m/s

Answers

Answer:

3000 kg meter per sec

Explanation:

Momentum of an object refers the motion of an object. Momentum depends upon mass and velocity both.

Formula to calculate the momentum of any object is,

Momentum = Mass × Velocity

By substituting values of mass and velocity of the shark from the question,

Momentum of shark = 200 × 15

                                  = 3000 kg meter per second

Therefore, shark weighing 200 kg has the momentum as 3000 kg meter per seconds.

Which object has the most thermal energy?
A. A 6 kg rock at 15°C
B. A 6 kg rock at 10°C
C. A 10 kg rock at 10°C
D. A 10 kg rock at 15°C

Answers

Answer:

D. A 10 kg rock at 15°C

Explanation:

Thermal energy is heat energy, meaning that the hotter rocks will have more energy.

The heavier/larger rocks can store more energy.

So if we combine the largest two variables, we get a 10kg rock at 15°C.

c.12.1 s
D.5.4 s

Answers

Answer:

use first equation of motion v=u+at..v is 0..since we have to take him to rest and u is 13.5

Explanation:

u = 13.5 m/s

a = - 2.5 m/s^2

v = u + at

0 = 13.5 - 2.5 * t

t (time to reach a complete halt) = 5.4 sec

A car accelerates at 3 m/s*2. Assuming the car starts from rest, how much time does it need to
accelerate to a speed of 12 m/s?

3 sec
2 sec
4 sec
12 sec
None of the other answers

Answers

Given:-

Acceleration,a = 3 m/s²

Initial velocity,u = 0 m/s

Final velocity,v = 12 m/s

To be calculated:-

Calculate the time take by a car.

Solution:-

According to the first equation of motion:

v = u + at

★ Substituting the values in the above formula,we get:

⇒ 12 = 0 + 3 × t

⇒ 12 = 3t

⇒ 3t = 12

⇒ t = 12/3

⇒ t = 4 sec

We are given with some parameters used in Kinematics for determining the motion of an object.

Accleration = 3 m/s²Started from rest (Initial vel.) = 0 m/sFinal velocity = 12 m/s

We have to find the time taken by the car to attain the final velocity with the given accleration. By using 1st equation of motion which says:

v = u + at

Final velocity = Initial velocity + Accl. × Time taken

Plugging the values,

➝ 12 = 0 + 3(t)

➝ 3t = 12

➝ t = 4 s

So, the correct answer is Option C. And we are done...

Irene was investigating the behavior of gases at certain conditions. Which would most likely cause an increase in the rate of collisions between gas molecules in a container?

Answers

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

Answers

Answer:

C-D

Explanation:

As you can see from the graph, the distance from A to B was from 0 m to 6 m in a duration of 3 seconds.

Divide 6 meters by 3 seconds to find the speed:

6 ÷ 3 = 2 m/s

B-C is not moving due to a straight line as said in the graph, so speed is

0 m/s.

There is also C-D since the car traveled from a distance of 9 meters

(6 -(-3) = 9) in 3 seconds too. (NOTE: The graph line going down does not mean it is slowing down, but rather going to a certain distance like going backwards)

Divide 9 meters by 3 seconds to get the speed:

9 ÷ 3 = 3 m/s

Between A-B, B-C, and C-D, C-D has the fastest speed recorded with 3 m/s.

A-D does not count here as the line has no connection between point A and point D.

A chemical reaction is a procedure that causes one group of chemical components to change chemically into another.

Chemical reactions, which can frequently be described by a chemical equation, traditionally include changes that only affect the locations of electrons in the formation and dissolution of chemical bonds between atoms, with no change to the nuclei (no change to the elements present).

The study of chemical processes involving unstable and radioactive elements, where both electronic and nuclear changes may take place, is known as nuclear chemistry.

10. John has borrowed his parents car without permission and is driving without a license. He
sees them out walking and realizes that they will be home in about 45 seconds. He is 500 m
from home and driving 25 m/s. Will he get to the driveway before they do?

Answers

Yes

Explanation:
John is driving at 25 meters per second and he has to drive 500 meters to get to his house.
I divided 500 by 25 to see how long it would take for John to get to his house
- 500/25= 20

Therefore, it will take John 20 seconds to reach his driveway, which is 25 seconds less than how long it will take his parents- so he will get to the driveway before them.
