Tectonic plates under the ground ,either go on top of each other or crash.
Answer:
m = 0.164 kg
Explanation:
T (period)
k (force/spring constant)
m (mass)
T = 2*Pi*sqrt(m/k)
T/(2*Pi) = sqrt(m)/sqrt(k)
(T/(2*Pi))*sqrt(k) = sqrt(m)
m = ((T/(2*Pi))*sqrt(k))^2
m = 4.5*((1.2/(2*Pi)))^2
m = 0.1641403175
Answer:
time period is increased so the clock will become SLOW
Explanation:
As we know that the time period of the simple pendulum is given by the formula
here we know that
L = distance of the pendulum bob from the hinge
g = acceleration due to gravity
now here the bob slide down so that the length of the pendulum is being increased
so time period T of the pendulum is also increased
so here the pendulum will take more time to oscillate or to complete one oscillation
so clock will become SLOW
An ecosystem can only sustain so many organisms. That limit would be its <span>carrying capacity. If the population goes above that number then other factors will cause the population to crash and then rebound to a constant level. </span>
Answer:
The maximum height is 0.33 m.
Explanation:
initial velocity, u = 8 m/s
final velocity, v = 0 m/s
10% of kinetic energy is lost in friction.
The kinetic energy used to move up the top,
KE = 10 % of 0.5 mv^2
KE = 0.1 x 0.5 x m x 8 x 8 = 3.2 m
Let the maximum height is h.
Use conservation of energy
KE at the bottom = PE at the top
3.2 m = m x 9.8 x h
h = 0.33 m
