Answer: D Demetrius who sees distortions and colors when he looks at a face.
Explanation:
Answer:
you didnt state if its a parallel or a series circuit
Explanation:
if in series
add the Resistance
Rt = R1 + R2 + R3
Rt = 4 + 6 + 2
Rt = 12ohms
however if in parallel.
1/Rt = 1/R1 + 1/R2 + 1/R3
We can solve the problem by using conservation of energy.
In fact, initially the projectile has only kinetic energy, which is given by
where m is the projectile's mass while
is its initial velocity.
At the point of maximum height, the speed of the projectile is zero, so it only has gravitational potential energy which is equal to
where g is the gravitational acceleration and h is the maximum height of the projectile.
Since the energy must be conserved, we can equalize K and U to find the value of h:
To answer this question, we will use the law of conservation of momentum which states that:
(m1+m2)Vi = m1V1 + m2V2 where:
m1 is the mass of the woman = 50 kg
m2 is the mass of the cart = 10 kg
Vi is the initial velocity (of woman and cart combined) = 5 m/sec
V1 is the final velocity of the woman = 7 m/sec
V2 is the final velocity of the cart that we need to calculate
Substitute with the givens in the above equation to get the final velocity of the cart as follows:
(50+10)(5) = (50)(7) + (10)V2
10V2 = -50
V2 = -5 m/sec
Note that the negative sign indicates that the cart is moving in an opposite direction to the others.
