It’s gonna be 13v is your answer
Answer: The speed at which Maya threw the snowball at Max is 20m/s
Explanation:
Given that
Mass of snowball= 1.5-kg.
Mass of Maya= 12kg
Initial speed of Maya=2.5m/s
We use the law of conservation of momentum to calculate the speed of the snowball which depends on its own mass, the mass of Maya who threw the snowball and the initial velocity at which the snowball was thrown by Maya
Ms x Us = Mm x Um
Mass of snowball x Initial speed of Snow ball =Mass of Maya x Initial speed of Maya
1.5kg x Initial speed of Snow ball =12 kg x 2.5m/s
Initial speed of Snow ball=( 12 kg x 2.5m/s) /1.5kg
Initial speed of Snow ball =20m/s
Answer:
q2 must also be doubled
r may also be halved
Explanation:
According to Coulumbs law
F= K q1 q2/r^2
If q1 is doubled, we must necessarily double q2 and r may also be halved in order to maintain F at the same value. Once the value of F is thus kept constant and E is also constant, the product FE must remain constant.
Answer:
L = 1.023 H
Explanation:
given,
radius of the cylindrical solenoid = r = 0.6 m
Number of turns = N = 600
Length = l = 0.5 m
Current in the cylindrical solenoid = 15 A
Inductance in the coil = ?
using formula
L = 1.023 H
the inductance L of the coil is = 1.023 H
-- "Tesla" is a unit for the strength of a magnetic field.
The Earth's magnetic field at the surface ... the one that makes
compasses work ... averages roughly 45 microteslas.
So 1 Tesla = somewhere around 20,000 times the magnitude
of Earth's magnetic field at the surface.
There's a smaller, more convenient unit, called the 'Gauss'.
1 Tesla = 10,000 Gauss. The Earth's magnetic field ranges
between 0.25 to 0.65 Gauss at various places on the surface.
-- Newton is a unit of force, equal to about 3.6 ounces.
1 pound of force is about 4.45 newtons.
