True. Think of a magnet and how they only connect to the opposite charges.
Non- mechanical wave does not need matter to carry energy.
e.g:- Light
Experiments and investigations must be B. Repeatable.
2m/s²
Explanation:
Given parameters:
Radius = 50m
Speed = 10m/s
Unknown:
Acceleration of the cyclist
Solution:
The acceleration of the cyclist is directed inside of the corner because his motion is inward. This is a form of centripetal acceleration;
Centripetal acceleration is given by;
a =
v is the velocity
r is the radius
a = = 2m/s²
