true
Explanation:
a wheelbarrow has its load situated between the fulcrum and the force the wheel Barrow is 2nd class because of its resistance between the force and the axis

Answer:
as the period decreases, the frequency and energy of the wave increase
Explanation:
Electromagnetic waves are oscillations of the electric and magnetic fields, described by maxwell's equations, the speed of the wave is called the speed of light
c = λ f
E = E cos (kx - wt)
Angular velocity is related to frequency and period.
w = 2π f = 2π / T
Let's analyze what happens when the wave period decreases, angular velocity and frequency increase.
This increase in frequency is reflected with the Planck equation in wave energy
E = h f
Therefore the wave carries more energy and can lead to stronger interactions with matter.
In summary, as the period decreases, the frequency and energy of the wave increase
Answer:
The distance the car traveled during the given time is 94.44 m.
Explanation:
Given;
time of motion t = 8 seconds
initial velocity, u = 15 km/hr = 4.167 m/s
final velocity, v = 70 km/hr = 19.444 m/s
The distance traveled by the car during this time is given by;
Therefore, the distance the car traveled during the given time is 94.44 m.
