Answer:

When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.Explanation:

Distance and mass. Distance affects gravity between objects and the mass because if they are the same weight, they would be equal in gravity, but if one was lighter and one was heavier, the heavier one would have more of a gravitational pull on the other one.

Two blocks of clay, one of mass 1.00 kg and one of mass 7.00 kg, undergo a completely inelastic collision. Before the collision

RideAnS [48]

Answer:8 m/s

Explanation:

Given

$m_1=1 kg$

$m_2=7 kg$

kinetic Energy of $m_1=32 J$

initially $m_2$ is at rest and let say $m_1$ is moving with velocity u

kinetic Energy of $m_1 is =\frac{m_1u^2}{2}=32$

$u^2=64$

$u=8 m/s$

In Completely inelastic collision both mass stick together and move with common velocity

Suppose v is the common velocity

$m_1u+0=(m_1+m_2)v$

$v=\frac{1\times 8}{1+7}=1 m/s$

therefore Final velocity with which both blocks moves is 1 m/s

How will the solubility of a gas solute change if the pressure above the solution is reduced?

Hoochie [10]

If the pressure above a solution containing a gas solute is reduced, the limit of the gas's solubility will decrease.

What is the lift (in newtons) due to Bernoulli's principle on a wing of area 76 m2 if the air passes over the top and bottom sur

AveGali [126]

Answer:

So lift will be 30.19632 N

Explanation:

We have given area of the wing $a=76m^2$

We know that density of air $d=1.29kg/m^3$

Speed at top surface $v_2=290m/sec$ and speed at bottom surface $v_1=150m/sec$

According to Bernoulli's principle force is given by

$F=A\times d\times \frac{v_2^2-v_1^2}{2}=76\times 1.29\times \frac{290^2-150^2}{2}=3019632N$

A sound wave of 70 cm travels 840 m in 2.5 sec. What is the velocity and frequency of sound?

Darya [45]

-- Speed = (distance) / (time to cover the distance) = 840/2.5 = 336 m/s

-- Frequency = (speed) / (wavelength) = 336/0.70 = 480 Hz.
