Answer:
a = 2 m/s2
Explanation:
we know from newtons 2nd law
F = ma.
we also know that from hookes law we have
F = kx
equate both value of force to get value of acceleration
kx = ma,
where,
k is spring constant = 8.0 N/m
x is maximum displacement 0.10 m
m is mass of object 0.40 kg
a = \frac{kx}{m}
= \frac{8 *0 .10}{0.40}
a = 2 m/s2
Answer:
B
Explanation:
The whole thing is talking about the damage runoffs have done that is equal to answer B.
Answer:
Force and displacement.
Explanation:
Work done is positive when we push table and it move in the direction of applied force.
The width is 2.5 cm long and could not be the right answer
Wave speed = (wavelength) x (frequency)
= (4 m) x (2 /sec)
= 8 m/sec
