Answer:

B.) In a series circuit, as light bulbs are added, the bulbs dim.

Explanation:

In a series circuit, as light bulbs are added, the bulbs dim. In a series circuit the bulbs are wired in a line. As more bulbs are added in series, the current flowing through all the bulbs decreases. The bulbs then dim as more are added

When two objects interact, the change in momentum of the first object is ______ the change in momentum of the second object.

Mariulka [41]

Answer:

A. Equal to and Opposite

Explanation:

when there is no External force acting on the system of bodies then Net momentum of the system is Conserved .

Given that there are 2 bodies

Let P₁ as first object's momentum

P₂ as second object's momentum.

Total Momentum =P₁ + P₂

As there is no external force acying on the system

Change in the Total momentum is zero

so,

0 = Δ P₁ + ΔP₂

ΔP₂ = -ΔP₁

negative sign indicates opposite direction.

Both are of equal magnitude.

A car drives at a constant speed of 21 m/s around a circle with radius 100 m. What is the centripetal acceleration of the car?

Sauron [17]

If you look below, we are using the centripetal acceleration formula. You just need to plug your numbers in and it should work! $A_c = \frac{v^2}{r} \\A_c=\frac{21^2}{100} \\A_c=\frac{441}{100} \\A_c= 4.41m/s/s$
