Yes it is. Uh huh, uh huh, shore enuff. Mmm hmm. Yeah yeah yeah. Yah Mon ! Indubitably.
<span>The larger the current flowing in a wire, the stronger the magnetic field
is that surrounds the wire.
That's why, if you want to make an electromagnet stronger, one way to
do it is to add another battery. By increasing the voltage, you'll increase
the current flowing in the coils of wire, and the electromagnet will be stronger.</span>
The substance which is a liquid fuel used in rocket engines is liquid oxygen. The correct answer is A.
Answer:
Force will be acting southward and the magnitude of force will be 1000 N
Explanation:
given,
mass of car = 1000 Kg
initial speed of the car (u) = 20 m/s
final speed of the car (v) = 0 m/s
distance to stop the car = 200 m
using equation of motion
v² = u² + 2 a s
0 = 20² + 2 x a x 200
400 a = -400
a = -1 m/s²
Now, we know
Force = mass x acceleration
F = 1000 x -1
F = -1000 N
- ve sign of force represent force will be acting in the opposite direction of motion.
Force will be acting southward and the magnitude of force will be 1000 N
The Ammeter shows: I = 15 A,
The circuit resistance is R = 0.2 Ohms.
By the Ohm`s Law:
R = V / I or:
V = I · R
V = 15 A · 0.2 Ohms
V = 3 V
Answer: C ) 3 V.
