Physics

Answer:

2.8351×10^7 N/kg

Explanation:

We know that,

W = mg -------(1)

where W = weight, m = mass, g = gravitational acceleration

Also from Newton's law of gravitation we know that,

F = GMm/r²

Where,

F = gravitational force,

G = universal gravitational constant

M,m = masses of object under gravitational influence

r = distance between the two center of masses.

Here we get

F = (Gm/r²)M -------(2)

From 1 and 2

The acceleration due to gravity = gravitational field intensity

So if you consider the gravitational field intensity at the surface of the asteroid,it is equal to the acceleration due to gravity at the same place.

So we get,

g = (6.67×10^-11)×9.3835×10^20/(47²) = 2.8351×10^7 N/kg

A bullet of mass m 1 is fired into a rod of length L and mass m 2 which is pivoted on one end and rests on a frictionless horizo
Reptile [31]

Answer:

The angular speed of the rod is w=(\frac{9m_{1}v_{i}  }{4m_{2}L } )(1-\frac{1}{\sqrt{2} } )

Explanation:

The final kinetic energy is:

\frac{1}{2} mv_{f}^{2}  =\frac{1}{2}(\frac{1}{2}  mv_{i}^{2}  )

Clearing vf:

v_{f} =\frac{1}{\sqrt{2} } v_{i}

The conservation of angular momentum before and after collision is:

m_{1} v_{i} (\frac{3L}{4} )=Iw+m_{1}v_{f} (\frac{3L}{4} )

Clearing w:

w=(\frac{9m_{1}v_{i}  }{4m_{2}L } )(1-\frac{1}{\sqrt{2} } )

Two waves are superposed. One wave has an amplitude of 3 cm, and the other has an amplitude of 4 cm. What is the resultant ampli
Luba_88 [7]
Superposition is a principle in physics. Applied to waves, it states that the amplitude of two superposed waves is the sum of the amplitudes of the two individual waves. Then the resultant amplitude of these two waves is 4 cm + 3 cm = 7 cm.

When its 75 kW (100 hp) engine is generating full power, a small, single-engine airplane with mass 700 kg gains altitude at a ra
bearhunter [10]

Answer:

Fraction of engine is 0.23

Explanation:

Given Data

m=700 kg

v=2.5 m/s

Fraction=?

Solution

Work done against gravity is given as

P=Fv

where F=mg

So

P=mgv

P=(700kg)×(9.8m/s^{2})×(2.5m/s)

P=17.15 kW

To find Fraction

\frac{17.5}{75}=0.23

Choose all the answers that apply. Power is calculated using ___.
antiseptic1488 [7]

Time , Work, Horsepower

Explanation:

In General, Power is defined as rate of doing work in physics.

1.) By work and Time, we can calculate power as follows,

                 Power = Work done per unit Time

                              = Work done / time

2.) From Horsepower we can directly get the power.

Horsepower (hp) is a unit to measure the  power, or the rate at which work is done, usually in  the output of engines or motors. There are many  types of horsepower. Two common ways of defining horsepower is being used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts.
