The sun is by far the largest object in solar system.containing99.8 percent of the solar system's mass.it shed most of the heat and light that makes life possible on earth and possibly elsewhere.planets orbit the sun in oval-shaped paths called ellipses,with the sun slightly off center of each ellipse
0.8 seconds
Explanation:
time of flight = 2u/g
u=4m/s
g=10
= 8/10
= 0.8 sec
just a trial...not sure!!!
Kinetic energy is energy in motion and potential energy is energy that is stored.
Answer:
Explanation:
The hand throwing ball moves on a circular path having radius r = .55 m
mass of ball m = .19 kg
velocity v = 70 mph
= 70 x 1600 / 60 x 60
= 31.11 m /s
centripetal force
= mv² / r
= .19 x 31.11² / .55
= 334.34 N
Answer:
Hi,
It states that the in linear systems, two or more stimuli cause a net stimulus that is equal to the sum of the individual responses. Applying the principle of superposition to waves, two waves of the same magnitude at a point in space add up to form a resultant displacement at that point which equals the sum of the two vectors.
Explanation
When two or more waves meet, they can interact to form a bigger wave or cancel out. In both cases, the resultant effect is caused by a combination of the two. This principle is applied in noise cancelling headphones that capture and cancel the noise around you by playing an opposite sound that ensures the cancelling of the destructive noise.
Best wishes!
