As a 5.0 x 10^2 newton basketball player jumps from the floor up toward the basket, the magnitude of the force of her feet on the floor is 1.0 x 10^3 newtons. As she jumps, the magnitude of the force of the floor on her feet is1) 5.0 x 10^2 N
2) 1.0 x 10^3 N
3) 1.5 x 10^3 N
4) 5.0 x 10^5 N

Answers

Answer:

2) 1.0 x 10^3 N

Explanation:

As a 5.0 x 10^2 newton basketball player jumps from the floor up toward the basket, the magnitude of the force of her feet on the floor is 1.0 x 10^3 newtons. As she jumps, the magnitude of the force of the floor on her feet is

1) 5.0 x 10^2 N

2) 1.0 x 10^3 N

3) 1.5 x 10^3 N

4) 5.0 x 10^5 N

The answer is B , because from newton's third law of motion which states that action and reaction are equal and opposite.

so the reaction of the floor on her leg will be equal to the the magnitude of her feet on the floor, this will hold if the floor does not collapse.
I believe the answer is (4) The reason that is, is because if the exponents are the same like 10^2 and 10^3, you can add them. Then you would get 10^5. You can go ahead though and multiply 5.0 and 1.0. Now remember that with decimals you don't need the zeros behind the decimal point. So that simplifies it with just 5 x 1. Leaving you with 5.0 x 10^5. 

A bike moves. 50 m in 10 seconds calculate the speed of the bike

Answers

The speed of the bike is calculated by dividing the total distance travelled by the total time taken, which in this case is 50 meters divided by 10 seconds. This yields a speed of 5 meters per second.

This involves a concept from Physics called speed.

Speed is defined as the distance covered by an object divided by the time taken to cover that distance.

Since the bike moves 50 meters in 10 seconds, to calculate the speed:

Identify the distance covered which is 50 meters.

Identify the time taken which is 10 seconds.

Divide the distance by the time to get the speed = 50 m / 10 s = 5 m/s. So, the speed of the bike is 5 meters per second.

#SPJ2

Answer:

We know that

Speed = Distance/ Time

Explanation:

  • Distance is 50 m
  • Time is 10 seconds

Speed = 50/10

= 5 m/s

Arun places a beaker of water on a hotplate and turns the hotplate on. The temperature in the room is 25 ºC. After the water heats to 75 ºC, she adds pieces of ice to the beaker. Which mode of transfer of heat energy occurs in the water during this experiment? Justify your answer

Answers

Answer:

Thermal convection

Explanation:

When ice cubes are placed in water, ice cubes start melting. This is because water transfers its heat to ice cubes until the temperature becomes equal and the process is called "thermal Convection".

Thermal convection is the mode of transfer of heat energy that will occur when ice cubes will be added to the hot water and at the end of the experiment when both are at the same temperature, no ice cube will left.

Hence, the correct answer is "thermal convection".
