PLEASE PLEASE HELP!!
QveST [7]

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 :

v=f\lambda\\\\v=2\times 6\\\\v=12\ m/s      

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,

f=\dfrac{100}{5}\\\\f=20\ Hz

Frequency of a wave is 20 Hz.

Hello! Please I need help on 1. (C) I dont know the formula to get the Total height using Mechanical Energy
inna [77]

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)

a bowling ball has a mass of 6 kilograms. a tennis ball has a mass of 0.06 kilogram. how much inertia does the bowling ball have
Andreyy89

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
