Answer:
A
Explanation:
I think the number of kernels popped is depended on the brand of the microwave or it can be the brand of popcorn but the independent variable is the cause and the dependent variable is the effect
Explanation:
It will increase as according to the Newton gravitational law the force of attraction is directly proportional to the product of the masses and inversely proportional to the square of the distance separating them
In case of atoms it will increase the decrease
Answer:
D
Explanation:
Work done refers to the product of the Force and the distance moved by the object in the same direction as the force. The formula is given by:
W = F × D
W is the Work Done in J
F is the Force in N
D is the parallel distance in m.
Hence by applying the Formula, we get:
W = 55(10)
= 550
Hence <u>answer is D.</u>
Answer:
125 V
Explanation:
Given,
Power ( P ) = 500 W
Current ( I ) = 4 A
To fine : -
Potential difference ( V ) = ?
Formula : -
P = V I
V = P / I
= 500 / 4
V = 125 V
Therefore,
the potential difference across the ends of the heating element is 125 V.
The moment of inertia of a uniform solid sphere is equal to 0.448 .
<u>Given the following data:</u>
Mass of sphere = 7 kg.
Radius of sphere = 0.4 meter.
<h3>How to calculate moment of inertia.</h3>
Mathematically, the moment of inertia of a solid sphere is given by this formula:
<u>Where:</u>
- I is the moment of inertia.
Substituting the given parameters into the formula, we have;
I = 0.448 .
