Answer:
990 J
Explanation:
Kinetic energy is:
KE = ½ mv²
Given m = 55 kg and v = 6 m/s:
KE = ½ (55 kg) (6 m/s)²
KE = 990 J
Answer:
True
Explanation:
Johannes Kepler was a German astronomer, mathematician and astrologer. He proposed a model of the solar system which remains in use, with some modifications. Moreover, he developed the laws of planetary motion which explain how the planets move around the sun. This work was not only significant on its own, but it also provided the foundations for Newton's theory of universal gravitation.
Answer:
a=1.25m/s²
Explanation:
GIVEN DATA
vi=10m/s
vf=15m/s
S=5m
TO FIND
a=?
SOLUTION
by using third equation of motion
2as=(vf)²-(vi)²
2a(5m)=(15m/s)²-(10m/s)²
10m×a=225m²/s²-100m²/s²
10m×a=125m²/s²
a=
a=12.5m/s²
Answer:
A satellite goes into orbit by getting a ride with a rocket or the Space Shuttle. Gravitational pull and the velocity of the satellite help it remain in orbit.
Explanation:
Answer:
The three quantized particles are:
1. Electrons
2. Protons
3. Neutrons
Explanation:
Quantization can be defined as the conversion of a continuous quantity into discrete set of values.
It can also be defined as the concept which says that the particles exist as the smallest finite and discrete value known as quanta which not be divided further.
The three particles include:
1. The electron bound inside an atom have quantized momentum and energy.
2. The proton bound in the inside of a nucleus has energy in the quantized form only.
3. Also the nucleus bound neutron is also a quantized particle.
