Answer:
venus
Explanation:
its small and still its the hottest since it has carbon 4 oxide in its atmosphere
Answer:
h = 250 m
Explanation:
Given that,
The helicopter exerts 6480 N of force on the water while rising high enough to fly over a mountain.
The helicopter does
of work on the water lifting it.
We need to find how high does it lift the water. Work done is given by :

So, it can lift the water to a height of 250 m.
Explanation:
C is correct.
Newton second law states that force is directly proportional to acceleration with m being the constant of variation.

So


A is wrong, the constant g only happens in free fall or in vertical direction
B and D are wrong due to the mathematical error or equation error
Answer:
81.3ohms
Explanation:
Resistance is known to provide opposition to the flow of electric current in an electric circuit.
Power dissipated by the computer is expressed as;
Power = current (I) × Voltage(V)
P = IV... (1)
Note that from ohms law, V = IR
I = V/R ... (2)
Substituting equation 2 into 1, we will have;
P = (V/R)×V
P = V²/R.. (3)
Given source voltage = 100V, Power dissipated = 123W
To get resistance R of the computer, we will substitute the given value into equation 3 to have
123 = 100²/R
R = 100²/123
R = 10,000/123
R = 81.3ohms
The resistance of the computer is 81.3ohms
