A particle moves with a velocity    1 v 5j 3j 6k ms      under influence of a contact force  F 10i 10j 20k N.    
katrin2010 [14]

Answer:

P = 200 W

Explanation:

The expression for the power is

        P = W / t

the job

       W = F d

   

we substitute

      P = F d / t

      P = F. v

We apply this equation to our case where the velocity is

 v = (5 i + 3j + 6k) m / s

and the force is

 F = (10i + 10j +20 k) N

we substitute in the power equation, remember that the scalar product of the unit vectors is

i.i = j.j = k.k = 1 and the other products are zero

    P = 10 5 + 10 3 + 20 6

    P = 200 W

An uncharged capacitor and a resistor are connected in series to a source of emf. If E = 9.00 V, C=20.0μF , and R = 100ω , find
Levart [38]

Based on the values of E, C, and R, the maximum charge on the capacitor can be found to be 1.80 x 10⁻⁴ C.

<h3>What is the maximum charge?</h3>

The maximum charge on the capacitor can be found as:

= C x ( 10⁻⁶ / 1 μF) x E

Solving gives:

= 20.0 x ( 10⁻⁶ / 1 μF) x 9.00

= 1.80 x 10⁻⁴ C

In conclusion, the maximum charge is 1.80 x 10⁻⁴ C

A marble, a bowling ball, a basketball, and a baseball are all sitting on the top shelf of a display case. Which one has the gre
Katena32 [7]

Answer:

Bowling Ball

Explanation:

The potential energy depends on the factors: mass of the object and distance between the two objects. In this case the distance is between the ground and the balls. Here, the bowling ball is heaviest and its center of mass is farthest in comparison to other two balls. Thus, it has the greatest potential energy.
