Answer:
The answer is 904,000.
Kinetic energy=1/2mv^2.
1/2×1130×40^2.
1/2×1808000=904,000Joules.
Answer:
r = 16 Km
Explanation:
given
m_n= 1.67 x 10^-27 Kg
M_star = 3.88 x 10^30 Kg
A= M_star/m_n
A= 3.88*10^30/1.67 x 10^-27
A=2.28 *10^57 neutrons A = The number of neutrons
we use the number of neutrons as a mass number because the star has only neutrons. = 1.2 x 10-15 m
r = r_o*A^1/3
r = 1.2*10^-15*2.28 *10^57^1/3
r = 16 Km
Geostrophic winds blows parallel to the isobars. That is because the Coriolis force and pressure gradient force ( PGF ) are in balance. But near the surface the friction can act to change the direction of the wind and to slow it down. Coriolis force decreases at the surface and PGF stays the same. The difference in terrain conditions affects how much friction is exerted. Hills and forests force the wind to change direction more than flat areas. Answer: Friction reduces the speed so Coriolis is weakened.
The power that must be delivered to the object by the force is 50 W
Power is defined as the rate of doing work. The power of an object in relation to the force and velocity is given by the following equation:
Power (P) = Force (F) × velocity (v)
P = F × v
From the question given above, the following data were obtained:
- Force (F) = 10 N
- Velocity (v) = 5 m/s
- Power (P) =?
P = F × v
P = 10 × 5
<h3>P = 50 W </h3>
Thus, the power that must be delivered to the object by the force is 50 W
