If the climber is not accelerating then a=0. Then F=ma=0. This is because the upward force of the rope is equal and opposite to the force due to gravity. So the net (total) force is 0
To me I would most think the answer is A.
PLEASE GIVE BRAINLIEST!!!
Answer:
The acceleration increases.
Explanation:
From Newton's 2nd Law, we have . We can see that force is directly proportional to mass and acceleration. Therefore, as force increases, either mass or acceleration must increase as well, and vice versa. Since mass is maintained here, if you increase the force applied to the Frisbee, the acceleration will increase as well.
The given statement "An AED should only be used if a person is too tired to continue with chest compressions" is false.
Answer: Option B
<u>Explanation:</u>
Most people think that they are very tired after applying the compress for 2-3 minutes. When the compressor is tired, it tends to compress more slowly. For this reason, rescuers are advised to do compressions in every 2 min to prevent fatigue and optimise the compressions quality. This should only be done if the person does not show signs of life or is dead, does not respond and breathes normally.
For example, consider you come across the victim in a narrow place and you have two helpers: Rescuer 2 arrives with the AED (automated external defibrillator) and puts it on the opposite side from Rescuer 1, who does chest compressions. Rescuer 2 turns on the AED and fixes the electrodes to the victim's chest, connecting wires to the AED if necessary. Rescuer 1 can continue CPR (Cardiopulmonary resuscitation) by placing electrodes until the victim's heart rate has been analysed.
Answer:
Difference: The weak force tears an atomic nucleus apart.The strong force is what keeps the protons and neutrons in a nucleus held together, while the weak force is what makes radioactive particles decay.Or even simpler: The strong force keeps stuff together while the weak force helps stuff split up.
Similarities: Weak force allows quarks to turn into other quarks, which can turn a neutron into a proton and break up the nucleus. ... One big difference is that the particles/fields that are responsible for carrying the strong force are massless, whereas for the weak force they are quite massive (nearly 100 times the proton mass).
