Answer:
a loud explosive noise caused by the shock wave from an aircraft traveling faster than the speed of sound.
Explanation:
Answer:
9.21 m
Explanation:
because this is the answer
Answer:
P₀ = 5.76 x 10⁻² MW
Explanation:
given,
efficiency of the power plant = 32%
Power produced by the nuclear fission = 0.18 MW
the power plant output = ?
using formula of efficiency
where P is the power produced in the power plant
P₀ is the power output of the power plant
P₀ = 0.18 x 0.32
P₀ = 0.0576 MW
P₀ = 5.76 x 10⁻² MW
Power plant output is equal to P₀ = 5.76 x 10⁻² MW
KE depends on velocity. It is easier to answer this question in terms of the earth.
The closer the object (earth/comet) is to the sun, the faster it moves. that means that the fastest moving point would be as the comet/earth passes through point C.
The slowest speed would be the furthest away from the sun which is point A.
Answer: The faster the planet moves the greater the Kinetic Energy.
The Slower the planet moves, the less the KE.
Point A is where it is slowest with the lowest amount of energy.
Discussion
The formula for KE is KE = 1/2mv^2. The mass of the comet or earth is a constant. It doesn't change no matter which point the comet passes through. If v goes down KE will go down. If v goes up, KE goes up.
Answer:
D. Velocity
Explanation:
Vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity's magnitude. Although a vector has magnitude and direction, it does not have position.
Speed is a scalar quantity – it is the rate of change in the distance travelled by an object, while velocity is a vector quantity – it is the speed of an object in a particular direction.
