Answer:
a= 92. 13 m/s²
Explanation:
Given that
Amplitude ,A= 0.165 m
The maximum speed ,V(max) = 3.9 m/s
We know that maximum velocity in the SHM given as
V(max) = ω A
ω=Angular speed
A=Amplitude
ω=23.63 rad/s
The maximum acceleration given as
a = ω² A
a= (23.63)² x 0.165 m/s²
a= 92. 13 m/s²
Therefore the maximum magnitude of the acceleration will be 92. 13 m/s².
Answer:
In the electric field, the like charges repel each other, and the unlike charges attract each other, whereas in a magnetic field the like poles repel each other and the unlike poles attract each other.
Explanation:
Answer:
D. a nonrenewable resource
Explanation:
From the description given, helium is a non-renewable resource.
- A non-renewable resource is one in which cannot be replenished by natural processes as they consumed.
- They get depleted as they are removed from nature.
- Helium formation cannot match its consumption if exploited.
<span>If only one force is acting an object it can have zero acceleration but it cannot have zero velocity. This occurs because acceleration is a change in speed, therefore when one force is acting upon the object the speed will remain constant. It can't have zero velocity because if one force is acting upon it then it is moving and no matter what that means it will have a velocity that isn't zero.</span>
