The unit for measuring current is an " ammeter ".
The unit for measuring voltage is a " voltmeter ".
The unit of measure for electrical current is the " Ampere ".
The unit of measure for potential difference (voltage) is the " volt ".
Answer:
Direction 1: Force is Non-zero and Not- constant
Direction 2: Force is Non-zero but constant
Explanation:
Given:
The picture of the map is attached. ( Missing from the question ).
Find:
The effect of force as it travels along each direction.
Solution:
- We know the relationship between change in potential and the force acting on the charge particle is given by:
F = - q*dV/ dr
Where,
q : Charge of the particle
V : Volt potential
dV/dr : Potential difference along a direction.
Direction 1:
- The color code of the map changes as the particle moves along this direction. Each color code represents a potential difference. So as the particle moves between different potential difference then according to the relationship given above The force varies along varies as particle moves from one color to another. Hence, a non zero force but not constant.
Direction 2:
- In the direction 2, the charged particle moves along the same color. The potential difference for each color is constant. Hence, according to the relationship of potential difference and force. If potential difference is constant then the Electrostatic Force on the charge is also constant. Hence, Force is non-zero and constant.
I’m so sorry I needed points but I hope you get it right
Answer:
μ =tanθ
Explanation:=
The ratio of the force of static friction and the normal reaction is equal to tanθ. F=mgsinθ. R = mgcosθ.
μ=tanθ
If the kinetic energy of each ball is equal to that of the other,
then
(1/2) (mass of ppb) (speed of ppb)² = (1/2) (mass of gb) (speed of gb)²
Multiply each side by 2:
(mass of ppb) (speed of ppb)² = (mass of gb) (speed of gb)²
Divide each side by (mass of gb) and by (speed of ppb)² :
(mass of ppb)/(mass of gb) = (speed of gb)²/(speed of ppb)²
Take square root of each side:
√ (ratio of their masses) = ( 1 / ratio of their speeds)²
By trying to do this perfectly rigorously and elegantly, I'm also
using up a lot of space and guaranteeing that nobody will be
able to follow what I have written. Let's just come in from the
cold, and say it the clear, easy way:
If their kinetic energies are equal, then the product of each
mass and its speed² must be the same number.
If one ball has less mass than the other one, then the speed²
of the lighter one must be greater than the speed² of the heavier
one, in order to keep the products equal.
The pingpong ball is moving faster than the golf ball.
The directions of their motions are irrelevant.
