The formula for wave motion is speed of wave equals frequency times wavelength.v = f lambdarearrangingf = v/lambdaf = 0.6/0.02 = 60/2 = 30Hz, or cycles per second.
Answer:
43.3J
Explanation:
Given parameters:
Force = 10N
Distance = 5m
Angle = 30°
Unknown:
Work done = ?
Solution:
Work done is the force applied to move a body through a particular distance;
Work done = Force x distance cos Ф
Now insert the parameters and solve;
Work done = 10 x 5 cos 30 = 43.3J
Answer:
<h2>0.05 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 0.025 × 2
We have the final answer as
<h3>0.05 N</h3>
Hope this helps you
