You haven't said whether the two resistors are connected
in series or in parallel. It makes a difference.
-- If they are in series, then their combined effective resistance is
(3 + 2) = 5 ohms.
Current in the circuit is (voltage)/(resistance) = 1.5/5 = 0.3 Amp.
-- If they are in parallel, then their combined effective resistance is
(3 x 2) / (3 + 2) = (6/5) = 1.2 ohms.
Current in the circuit is (voltage)/(resistance) = 1.5/1.2 = 1.25 Amp.
Answer: The longer the lever, the greater the force on the load will be.
Explanation:
Answer:
10000N
Explanation:
Given parameters:
Mass of the car = 1000kg
Acceleration = 3m/s²
g = 10m/s²
Unknown:
Weight of the car = ?
Solution:
To solve this problem we must understand that weight is the vertical gravitational force that acts on a body.
Weight = mass x acceleration due to gravity
So;
Weight = 1000 x 10 = 10000N
The metal ball lost energy while the putty ball gained energy.
<h3>What is momentum?</h3>
Momentum is the product of mass and velocity of the body. We must note that momentum before collision is equal to momentum after collision.
1) Kinetic energy before collision = 1/2mv^2 = 0.5 * 6 * 4 = 12 J
2) kinetic energy after collision = 0.5 * 6 * 2= 6 J
3) Kinetic energy of putty ball = 0.5 * 6 * 2= 6 J
4) Energy lost by the metal ball = 12 J - 6 J = 6 J
5) Energy gained by the putty ball = 6 J - 0J = 6 J
6) The rest of the energy was converted to heat after the collision.
