The ratio of intensity to distance is an inverse square law so if you increase the distance by 3 times, the intensity will reduce by
times
so the intensity will be 9 times less.
Friction force is equal to the applied force F until the block starts moving. Hence, it will increase until the maximum value of 3.0*10*0.50=150 N.
While it's moving, the friction will be 3.0*10*0.2 = 60 N, constant. The rest of the applied force will accelerate the block.
Answer:
R = 0.24 kilo-ohm
Explanation:
Given that,
Voltage, V = 12 volt
Current, I = 50 mA = 0.05 A
We need to find the resistance of the resistor. We can find it using Ohm's law. So,
V = IR
or
R = 0.24 kohm
So, the value of resistance is 0.24 kilo-ohm.
Ok so Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion. It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion.
If 2 children are both pulling on the toy and giving the same amount of Newton’s then nothing would change. If one child is giving more Newton’s then that Child would end up with the toy.
I hope this helped. I didn’t really know how to explain it. <3
In cold winter day, the body temperature falls down from normal temperature of 98.6°F (37°C) to 95°F (35°C). In winter body losses heat faster than it generates heat. If the temperature fall further below 95°F (35°C), it is emergency condition known as Hypothermia. One has to consult doctor in this case.
In summer hot days, body evaporates water in the form of sweat, in order to remain itself cool. Rise of temperature up to 100°F is normal. It is recommended to hydrate body to maintain temperature in summer days.
