Answer:
s = vcos(x)t
50 = 25cos(45)t
cos(45)t = 2
t = 2/cos(45) = 2sqrt(2)
h = vsin(x)t + gt^2/2
h = 25sin(45)*2sqrt(2) - 4.9*8
h = 10.8 metres
Explanation:
Infared = used by police
gamma = short wavelength
radio = largest wavelength
visible = only ones we can see
Laws and theories are similar in that they are both scientific statements that result from a tested hypothesis and are supported by scientific evidence.
It is strong enough to penetrate through flesh but not bone so we can see if there are fractures or breaks in our skeleton
