B- Same force
It’s b because force always acts in equal but opposite pairs.
Answer:
Amplitude = 0.058m
Frequency = 6.25Hz
Explanation:
Given
Amplitude (A) = 8.26 x 10-2 m
Frequency (f) = 4.42Hz
Conversation of energy before split
½mv² = ½KA²
Make A the subject of formula
A =
Conversation of energy after split
½(m/2)V'² = ½(m/2)V² = ½KA'²
½(m/2)V² = ½KA'²
Make A the subject of formula
First divide both sides by ½
(m/2)V² = KA'²
Divide both sides by K
V² = A'²
= A'
Substitute for A in the above equation
A' = A/√2
A' = 8.26 x 10^-2/√2
A' = 0.05840702012600882
Amplitude after split = 0.058 (Approximated)
Frequency (f') = f√2
f' = 4.42√2
f' = 6.25082394568908011
Frequency after split = 6.25Hz (approximated)
Explanation:
The given data is as follows.
Spring constant (k) = 78 N/m,
Mass of block (m) = 0.50 kg
According to the formula of energy conservation,
mgh sin
h =
=
= 0.64 m
Thus, we can conclude that the distance traveled by the block is 0.64 m.
Answer:within the focal length of the lens, provided the focal length is shorter than the near point distance.
Explanation:Hope it helps
