Answer:
Kinetic energy at 0.05 m is 0.037 J
Explanation:
Given:
Mass, m = 2 kg
Spring constant, k = 10 N/m
Amplitude, A = 0.1 m
Angular frequency, ω = √k/m
Substitute the suitable values in the above equation.
ω = 2.24 s⁻¹
Simple harmonic equation is represent by the equation:
x = A cos ωt
Substitute 0.05 m for x, 0.1 m for A and 2.24 s⁻¹ for ω in the above equation.
t = 0.47 s
Kinetic energy at x = 0.05 is determine by the relation:
Substitute the suitable values in the above equation.
E = 0.037 J

Answer:It shows the size of the range of the moisture contents at which the soil remains plastic. In general, the plasticity index depends only on the amount of clay present. It indicates the fineness of the soil and its capacity to change shape without altering its volume.
Answer:
Total time= 2.56 s
Explanation:
Given that
So distance = 386242560 m
Velocity of light
We know that
Distance = velocity x time
Now by putting then values
t=1.28 s
So the total time = 2 x 1.28
total time= 2.56 s
Answer:
c. turn downward
Explanation:
From the information given:
To find the tendency of the sander;
We need to apply the right-hand rule torque; whereby we consider the direction of the flywheel, the direction at which the torque is acting, and the movement of the sander toward the right.
Since the flywheel of the sander is in counterclockwise movement, hence the torque direction will be outward placing on the wall. However, provided that the movement of the sander is toward the right, then there exists an opposite force that turns downward which showcases the tendency in the sander is downward.
