<span> The meteor accelerates after it is brought into earths force field
</span>
Answer:
0.82 m
Explanation:
We are given that
Weight,
=225 N
Length,l=5 m
d=1.1 m
We have to find the distance x for which person weighs 385 N walk on the overhanging part of the plank before it just begins to tip.
Half length=


When system in equilibrium then




Answer:The answer is option C, the point A
Explanation:Just did it
Answer:
33.516 kJ
Explanation:
Potential energy is given by:
PE = mgh
Where m is the mass, g is acceleration due to gravity, and h is the height. In this case:
PE = 38kg x 9.8m/s^2 x 90m = 33516 kg m^2/s^2 = 33516 J = 33.516 kJ
energy moves through the sun in two main way, Radiation and Convection.
Explanation:
as the energy moves outward from the sun's core, 1st enters rhe radiation zone. the radiation zone is a region of highly compressed gas. here the energy is transferred by the absorption and irradiation of electromagnetic waves
