Answer:
If you ring the doorbell and no one opens the door, you'll infer that no one is home rather than continuing to ring the doorbell to an empty house. Being able to understand this and look for another solution is another example of mental flexibility.
Explanation:
I think you are asking if fm radio waves follow a wave motion and if so, the answer is yes
<u>The following proposals would make the scientist to accomplish this goal:</u>
- decreasing the distance between Hox and Blox
- increasing the mass of Hox
- increasing the mass of Hox and Blox
Answer: Options A, B, and E
<u>Explanation:</u>
The gravitational pull on an object by another, is nothing but the force that it exerts due to its gravity. Earth has gravity, so it pulls down everything that tends to move up. Similarly, Hox and Blox have gravitational pulls on each other, due to their gravitational forces.
Where,
F = force exerted on object
G – Gravitational constant
– Mass of two objects
r – Distance between two objects
This gravitational pull varies in phase with the mass of two bodies in relation, and inversely proportionate to the distance square. Hence, the scientist could do less the distance between the bodies, or else, spend to increase the size of one of them or both the bodies.
The tensions in the supporting ropes combine to equal zero, if the tensions are equal.
<h3>
Tension exerted by Burl and Paul </h3>
The sum of the tension exerted by Burl and Paul is determined as follows;
∑T = Ta + Tb
The net tension will be zero, when Ta is equal to Tb
0 = Ta - Tb
Ta = Tb
Thus, the tensions in the supporting ropes combine to equal zero, if the tensions are equal.

Answer:
20 m
Explanation:
We'll begin by calculating the kinetic energy of the mass. This can be obtained as follow:
Mass (m) = 10 kg
Velocity (v) = 20 m/s
Kinetic energy (KE) =?
KE = ½mv²
KE = ½ × 10 × 20²
KE = 5 × 400
KE = 2000 J
Finally, we shall the height to which the mass must be located in order to have potential energy that is the same as the kinetic energy. This can be obtained as follow:
Mass (m) = 10 kg
Acceleration due to gravity (g) = 10 m/s²
Potential energy (PE) = Kinetic energy (KE) = 2000 J
Height (h) =..?
PE = mgh
2000 = 10 × 10 × h
2000 = 100 × h
Divide both side by 100
h = 2000 / 100
h = 20 m
Thus, the object must be located at a height of 20 m in order to have potential energy that is the same as the kinetic energy.
