A weightlifter lifts a 1400 N barbell 2.5 meters. Calculate the work done during the lift

Answers

Answer: W = 3500 J

Explanation: Work is the product of the amount of force and the perpendicular distance or W = Fd.

W = Fd

= 1400 N ( 2.5 m )

= 3500 J

Answer:

Force = 1400N

Displacement = 2.5 m

work done = F×D

=1400×2.5

= 3500 joule

How are both radio waves and microwaves used for methods of communication?

Answers

Answer: Radio waves is a type for wave that is used to transmit television and radio programmes, while microwaves can be used for phone communication.

Explanation: Radio waves and microwaves are types of electromagnetic radiation that has the longest wavelengths and the lowest frequency and it carries the least amounts of energy. This causes it to interact with mostly nothing as it travels, therefore it is just easier to transmit information as there is no disturbance in the transmittion.

Radio waves and microwaves are types of electromagnetic radiation with the longest wavelengths, lowest frequency and carry the least amounts of energy. This causes it to interact with mostly nothing as it travels, therefore it is just easier to transmit information as there isn't any major disturbance in the transmittion. If it was any other type of radiation, the signal would be unclear and in most cases impossible to process.

a baseball bat is in contact with a ball for 0.02 seconds, and exerts a force of 400 newtons. what is the impulse on the ball?

Answers

Answer:

I=8 Nw.s

Explanation:

Impulse

It is a physical magnitude that measures the force applied to an object by the time that force is acting. It produces a change in the momentum of the object, which is expressed in the following formula

$I=\Delta p=m(v_2-v_1)=F.t$

We know the bat applies a force on the ball of F=400 N during t=0.02 sec, thus the impulse is

$I=(400) (0.02)=8\ Nw.s$

$\boxed{I=8\ Nw.s}$
