The Big Bang theory is matter and energy in the universe exploded out from one point. As the explosion occurred, energy and matter spread outward and formed the universe. The matter from the Big Bang formed clouds of gas.
Answer:
Spin a coil of wire inside a magnetic field or move a magnet inside a coil of wire.
Explanation:
This is according to Faraday's law of electromagnetic induction.
To solve this problem we will apply Newton's second law for which weight is defined as the product between mass and acceleration of gravity. That is to say
Here,
m = mass
g = Gravitational acceleration
If we have that 0.22lb is equal to 1N, then the weight will be
Gravitational force is equal to , then
Therefore the mass of the car is 1320.5Kg
Answer:
80 times 12=960
Explanation:
You have to do the equation for work, the equation is work= force times distance, the force here is 80newtons, the distance is 12meters, so you would do 80 times 12 to get your answer of 960
Answer:
5.0 m/s
Explanation:
The horizontal motion of the salmon is uniform, so the horizontal component of the salmon's velocity is constant and it is
where u is the initial speed and . The horizontal distance travelled by the salmon is
where d = 1.95 m and t is the time needed to reach the final point.
Re-arranging for t,
(1)
Along the vertical direction, the equation of motion is
where:
y = 0.311 m is the final height reached by the salmon
h = 0 is the initial height
is the vertical component of the initial velocity of the salmon
is the acceleration of gravity
t is the time
Substituting t as found in eq.(1), we get the equation
and we can solve this formula for u, the initial speed of the salmon:
