Explanation:
(1) We have,
Wavelength of a wave is 2 meters
Frequency of a wave is 6 Hz
It is required to find the velocity of a wave. The velocity of a wave is given by :
So, the velocity of a wave is 12 m/s.
(2)
Number of waves passing are 100
Time taken to pass the wave is 5 seconds
The frequency of wave is given by total number of waves passing per unit time. So,
Frequency of a wave is 20 Hz.
Magnetism is one aspect of the combined electromagnetic force. It refers to physical phenomena arising from the force caused by magnets, objects that produce fields that attract or repel other objects
Answer:
4.00m
Explanation:
at that instant where it is dropped all the mechanical energy is gpe which is 71.9
and the formula for gpe = mass (1.80) * height * gravitational field strength (i'm using 10 m/s2)
height of football stadium
= 71.9/[(1.80)(10)]
= 71.9/18.0
= 3.99444..
= 4.00 (3 sf)
Answer:
100 times
Explanation:
Since inertia is directly proportional to the mass of an object, the higher the mass the higher the inertia. In this case, 6 Kg is 100 times heavier than 0.06 Kg to imply The bowling ball has 100 times more inertia than the tennis ball because it has 100 times more mass
An object in motion changes position
