Answer:
the action of investigating something or someone; formal or systematic examination or research.
Explanation:
This definition is provided by Oxford Languages
To claculate the gravitational attraction between two bodies with mass 1(m1) and mass 2 (m2) you need to use the equation:
F= G ((m1*m2)/r^2)
Where;
G is the gravitational constant (6.67E-11 m^3 s-2 Kg-1) and
r is the distance between the two objects.
B. Electrical energy
Among the choices given, the type of energy associated with
electric currents is electrical energy. By its definition, electric current is
the flow of charged particles through a conductor or a conduction medium, for
example, a wire. Basically, it involves electricity. It is similar to water current
but instead of water molecules, charged particles move down a conductor. These
charged particles are mostly electrons which move freely and at random. When
all the free electrons move in the same direction, a current is created.
Answer:
The kinetic energy will be "399.65 J".
Explanation:
Given:
Mass,
m = 1.2 kg
Velocity,
v = 31.3 m/s
The total energy of mass will be:
⇒ 
or,
⇒ 
By putting the values, we get
Since,
The system's total energy is unchanged, then
⇒
or,
⇒ 
Answer:
129.96
At a Gravitational acceleration of 32.17405 ( which is the normal rate for a freefall) you will geta velocity of 129.96 and the time of fall will be 4.039 seconds from 80 meters.
Why is the weight of a free falling body zero? It is not, an object in free fall will still have a weight, governed by the equation W = mg, where W is the object's weight, m is the object's mass, and g is acceleration due to gravity. Weight, however, has no effect on an objects free falling speed, two identically shaped objects weighing a different amount will hit the ground at the same time.
Hope this helps!! If so please mark brainliest and rate/heart to help my account if it did!!
