Answer:
amplitude is 8.92 cm
speed of block is 44.11 cm/s
Explanation:
given data
mass = 0.650 kg
spring constant = 18 N/m
speed = 47 cm/s = 0.44 m/s
speed at x point = 0.350 A
to find out
amplitude of subsequent oscillation
solution
we know here conservation of energy
maximum kinetic energy = maximum potential energy
here we know k is spring constant and m is mass and A is amplitude and v is velocity
so solve it we get
A =
put here all these value
A =
A = 0.08931 m
so amplitude is 8.92 cm
and
by conservation of energy
initial energy = final energy
=
solve we gey V
V =
put here value Vm = 0.47 , and x = 0.350
V =
V = 0.4411 m/s
so speed of block is 44.11 cm/s
Answer:
KE= 1/2mv^2= 1/2*0.0042kg*993m/s= 2.0853joule
Answer:
<u>Option-(D):</u> 10¹¹ waves per second.
Explanation:
- <u>Electromagnetic waves:</u>
The electromagnetic waves is such form of a energy transfer or wave propagation through any space with or without having any medium(particles).As, the medium or particles inside a space are able to transfer the amount of energy from the origin towards the receiver, which makes it very easy for the wave propagation through a medium.Now, the electromagnetic waves are generated from the sensor on a traffic light when the frequency,f level of the wave generation is about 10¹¹ Hertz(Hz).
Answer:
A
Explanation:
Opposite attract. Since electrons are negative they will be attracted to the protons because they a positive
Answer:
Therefore, the situation in which both the instantaneous velocity and acceleration become zero, is the situation when the ball reaches the highest point of its motion.
Explanation:
When a ball is thrown upward under the free fall action of gravity, it starts to loose its Kinetic Energy as it moves upward. As the ball moves in upward direction, its kinetic energy gradually converts into its potential energy. As a result the speed of the ball starts to decrease as it moves up. Therefore, at the highest point during its motion, the velocity of ball becomes zero and it stops at the highest point for a moment, and then it starts to fall back down, under the influence of gravitational force.
Therefore, the situation in which both the instantaneous velocity and acceleration become zero, is the situation <u>when the ball reaches the highest point of its motion.</u>
