The answer is Nuclear Fusion. The sun emits energy by converting hydrogen into helium. Nuclear fusion does two things, it converts hydrogen into helium and it also converts mass to energy.
Answer:5 N
Explanation:
Given
A physics major is cooking breakfast when he notices that the frictional force between his steel spatula and his Teflon frying pan is only 0.200 N
And from tables of coefficient of Kinetic friction for Teflon is 
and Friction force is 
where N is the normal reaction
Answer:
Explanation:
From the question, we can see that the elevator is at a constant speed, invariably, acceleration is zero. And thus, there is no external force acting in the man, asides from force of gravitation acting on the man between those 5s. Now, we solve the question using newton's second law of motion.
The second law of motion states that, "the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object."
Summation Fy = ma(y)
F(n) - F(g) = 0
F(n) - mg = 0
F(n) = mg
F(n) = 77*9.81
F(n) = 755.37N
Answer:
The voltage (V)
Explanation:
Ohms, in his law, has explained the relationship between current, resistance and voltage.
Ohm's law, which states that the voltage passing through a resistor is directly proportional to both the current and the resistance of the resistor, has the following equation:
V = IR
Where;
V = voltage (volts)
I = current (Amperes)
R = resistance (ohms)
According to this question, Karl measures the current, I, through a resistor. In order to calculate his resistance, R, he will need to measure the voltage, V.
