Velocity=frequency(wavelength)
24m/s=f(2m)
24/2=f(2)/2
12Hz=f
Potential energy + kinetic energy = constant at every moment in time
At the highest point:
potential energy is at its maximum
kinetic energy is zero
Answer:
Explanation:
Btu of British thermal unit is a unit of heat. The relation between btu/year and watts is given by :
So, is equal to 11 kW. Hence, the correct option is (d).
Answer:
4.55 x 10⁹m
Explanation:
Given parameters:
Mass of object 1 = 3.1 x 10⁵kg
Mass of object 2 = 6.5 x 10³kg
Gravitational force = 65N
Unknown:
Distance between them = ?
Solution:
To solve this problem, we use the expression below from the universal gravitational law;
Fg =
G = 6.67 x 10⁻¹¹
65 =
Distance = 4.55 x 10⁹m
D
Because the rest of the answers are illogical
