Answer:
26m/s²
Explanation:
Given parameters:
Mass of the student = 60kg
Weight = 1560N
Unknown:
Acceleration due to gravity = ?
Solution:
Weight is a force on a body due to gravity;
Weight = mass x gravity
Insert the given parameters and solve;
1560 = 60 x gravity
Gravity =
= 26m/s²
Answer:
A. Direction
Explanation:
Velocity is the speed of something heading in a certain direction. If speed or direction changes, the velocity changes.
Answer:
A police radar gun uses X-band microwave radiation at a frequency of 13.1 GHz. Microwaves travel at the speed of light, or 3x108 m/s. Since the frequency shift will be small for practical car speeds and difficult to detect, the shifted frequency is compared to the original frequency, and the resulting beat frequency is used to determine the speed of the car.
a.) If Michael is traveling at 29 m/s, what is the resulting beat frequency that the radar gun detects?
ANSWER: 2533 Hz
Explanation:
The protons and neutrons
I think
They could all be 'used', but the Bunsen burner is the only one that <em>might</em> actually do the job it's designed for.
The scales and balances would be useless in space, because they all use gravity to do their jobs, and they don't work when they're falling.
