Answer:
Explanation:
The maximum velocity of an object moving in a curve beyond which it will slide off the curve is given by the relationship in equation (1);
where 
is the coefficient of friction between the object and the surface of the curve, g is acceleration due to gravity and r is the radius of the curve.
Given;
v = 0.8m/s
g = 
r = ?
In order to solve for , we can simply make it the subject of formula from equation (1) as follows;
since we were not given the value of r, we can just substitute other known values, then solve and leave the answer in terms of r.
Therefore;
Answer:
1 Frequency
2 Wavelength
3 Amplitude
4 Crest

The light must be either very dim or else non-existent.
We can't see the light wave or the label.
Answer:
potential energy is a type of energy an object has because of it's position
a wedge is a small inclined plane
a screw is an inclined lane wkich goes round a centrral axis ... like a 'spiral' or helical staircase
