A: w=mg w=13(9.8) w= 127.4
B: 13kg
C: w=mg w=13(1.6) w= 20.8
D: The force of gravity is less on the moon than on earth therefore making the dog weigh less.
Newton’s first law, an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Or in our case an object at rest will stay at rest until an outside force interferes.
Answer:
0.00915 m
Explanation:
= Wavelength of light = 610 nm
L = Distance of slit to screen = 1.5 m
a = Slit gap = 0.2 mm
Width of central maximum is given by

The width of the central maximum is 0.00915 m
A wave is like a transport of energy ( think sounds waves or light waves)
They can be measured by the amplitude and the wavelength
Answer:
1 watt power is defined as the 1 Joule of energy consumed per second..
