Kepler's three laws of planetary motion can be stated as follows: (1) All planets move about the Sun in elliptical orbits, having the Sun as one of the foci. (2) A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time.
Answer:
Induced current, I = 0.5 A
Explanation:
It is given that,
number of turns, N = 20
Area of wire, 
Initial magnetic field, 
Final magnetic field, 
Time taken, t = 2 s
Resistance of the coil, R = 0.4 ohms
We know that due to change in magnetic field and emf will be induced in the coil. Its formula is given by :
Where
Let I is the induced current in the wire. It can be calculated using Ohm's law as :
I = 0.5 A
So, the magnitude of the induced current in the coil is 0.5 A. Hence, this is the required solution.
A fuel injection system that does not use a sensor to measure the amount (or mass) of air entering the engine is usually called speed density type of system.
<h3>What is speed density fuel injection system?</h3>
Speed density fuel injection system is a fuel delivery method.
This system relies on a combination of sensor and an intake air temperature sensor to measure the amount (or mass) of air entering the engine.
Thus, a fuel injection system that does not use a sensor to measure the amount (or mass) of air entering the engine is usually called speed density type of system.

Answer:
b and e
Explanation:
r x F is the formula for torque.
The "turning effect" or torque happens when concentric forces rotate an object along said center.
a) False because T = Fr = Ia (a = angular acceleration)
b) True
c) False. L = Iw (w = angular velocity), which does not equal Ia
d) False. It is torque, not the product of torque and something else
e) True.
