Answer:
<h2>1.5 ohms</h2>
Explanation:
Power is expressed as P = V²/R
R = resistance
V = supplied voltage
Given P = 600W and V = 30V
R = V²/P
R = 30²/600
R = 900/600
R = 1.5ohms
magnitude of its resistance is 1.5ohms
Answer:
the density of indium is 7.2 g/cm^3
Explanation:
The computation of the density of indium is shown below:
Given that
Mass = 16.6 g
Volume = 48.6 c,^3 - 46.3cm^3 = 2.3 cm^3
Based on the above information
As we know that
Density = mass ÷ volume
So,
= 16.6g ÷ 2.3 cm^3
= 7.2 g/cm^3
hence, the density of indium is 7.2 g/cm^3
We simply applied the above formula so that the correct value could come
And, the same is to be considered
Answer:
D. 2^(3/2)
Explanation:
Given that
T² = A³
Let the mean distance between the sun and planet Y be x
Therefore,
T(Y)² = x³
T(Y) = x^(3/2)
Let the mean distance between the sun and planet X be x/2
Therefore,
T(Y)² = (x/2)³
T(Y) = (x/2)^(3/2)
The factor of increase from planet X to planet Y is:
T(Y) / T(X) = x^(3/2) / (x/2)^(3/2)
T(Y) / T(X) = (2)^(3/2)
Answer:
Yes, it would work.
Explanation:
From Flehmings left hand rule, current can be generated when a coil cuts the magnetic field of a powerful magnet. Thus, the spin of properller turns a generator thereby converts motion to electrical energy.
The major challenge would be how to set the car in motion when at rest. But this can be solved by energy consrvation process. The law of conservation of energy states that energy cannot be created or destoyed, but transformed from one form to another. Thus, there would be mechanism having a device called an inverter which stores electric energy when the vehicle is in motion. This regenerates the required initial energy to set the electric car in motion when at rest or stops.
The first collision because a greater amount of momentum must be taken and used in order to push the cart back, giving it a greater mass and impulse
