This is false. Your hypothesis, or prediction, is just that: a prediction. Saying its a failure will result in bias.
Answer:
b) 338 N
Explanation: let m be the mass of the gymnast and a be the acceleration of the gymnast.
the force required to accelerate the gymnast is given by:
F = m×a
= (45.0)×(7.50)
= 337.5 N
Therefore, the force a trampoline has to apply is 138 N.
Answer:
t = 120.5 nm
Explanation:
given,
refractive index of the oil = 1.4
wavelength of the red light = 675 nm
minimum thickness of film = ?
formula used for the constructive interference

where n is the refractive index of oil
t is thickness of film
for minimum thickness
m = 0


t = 120.5 nm
hence, the thickness of the oil is t = 120.5 nm
Answer:
A step down transformer is a device that can be connected to the switch and the appliance. There are two types of transformers that you should know about: step up and step down transformers. Step up transformers generally produce a higher output voltage than the input voltage.
