1 answer:
DaniilM [7]3 years ago
5 0

Use this formula where:

∝ is the average distance between the centers of the two bodies

G is the gravitational constant

M1 and M2 are masses of the parent body and the orbiting body respectively.

T-Joe (65 kg) is running at 3 m/s. T-Brud (50 kg) is running at 4 m/s. What would be T-Joe's momentum?
Debora [2.8K]

Answer:

P_J=195N

Explanation:

From the question we are told that

Mass\ of T-joe\ M_J=65\\Velocity\ of T-joe\ V_J=3m/s\\Mass of\ T-Brud\ M_B=50kg\\Velocity\ of T-Brud\ V_B=3m/s\\

Generally the equation for momentum is mathematically given by

P=mv

Therefore

T-Joe momentum P_J

P_J=65*3

P_J=195N

How do you know that forces are balanced when static friction acts on an object?
lyudmila [28]
By looking at the acceleration of the object.
In fact, Netwon's second law states that the resultant of the forces acting on an object is equal to the product between the mass m of the object and its acceleration:
\sum F = ma

So, when static friction is acting on the object, if the object is still not moving we know that all the forces are balanced: in fact, since the object is stationary, its acceleration is zero, and so the resultant of the forces (left term in the formula) must be zero as well (i.e. the forces are balanced).

What is a conductor
Soloha48 [4]

C. none of the above

An electrical conductor is a substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage. Conductivity, in general, is the capacity to transmit something, such as electricity or heat. ... Copper, steel, gold, aluminum, and brass are also good conductors.

A car starts from rest and uniformly acceleration to find speed of 20.0m/s in a time of 15.0 s . How far does the car travel dur
Diano4ka-milaya [45]

Answer:

The answer is:    

150 m

Explanation:

find acceleration first.

Vf = at + Vi

20 = a(15) + 0

a = 1.33m/s^2

x = 1/2at^2

x = 1/2 (1.33) (15)^2

x = 149.625m or round it to 150m

hope this helps
