Calculate the force exerted on the wall assuming that force is horizontal and using the data in the schematic representation of

the situation. Note that the force exerted on the wall is equal in magnitude and opposite in direction to the force exerted on the horse, keeping it in equilibrium. The total mass of the horse and rider is 675 kg. Take the data to be accurate to three digits.

As the temperature rises the solubility of all gases in water also ______
Anastasy [175]

Answer:

As the temperature rises the solubility of all gases in water also will decrease.  

Explanation:

The solubility of gases in water increase with the decrease of the temperature, and vice-versa.  

The scape of the gas molecules from solution occurs by the breaks of the intermolecular bonds as a consequence of the increase of the kinetic energy which causes an increase in the motion of the gas molecules in solution.                                                    

That is why as the temperature rises the solubility of all gases in water also will decrease.      

I hope it helps you!

How do you calculate the mass of an object accelerating at22.35m/s2 with a force of 120N
Arte-miy333 [17]

Answer:

The mass of object is calculated as 5.36 kg

Explanation:

The known terms to find the mass are:

           acceleration of object (a) = 22.35 m/s^{2}

                        Force exerted (F) = 120N

                        mass of an object (m) = ?

From Newton's second law of motion;

                                   F = ma

                           or, 120 = m × 22.35

                          or, m= \frac{120}{22.35} kg

                           ∴ m = 5.36 kg

What is the efficiency of an engine that exhausts 440 J of heat to a cold reservoir and receives 570 J of heat from a hot reserv
katrin2010 [14]

Answer:

Efficiency = 77%

Explanation:

Input energy = 570 J

Output energy = 440 J

To find the efficiency;

Efficiency = \frac {Out-put \; energy}{In-put \; energy} * 100

Substituting into the equation, we have;

Efficiency = \frac {440}{570} * 100

Efficiency = 0.7719 * 100

Efficiency = 77.19 ≈ 77%

Therefore, the efficiency of the engine is 77 percent.
