At the same moment, one rock is thrown upward at 4.5 m/s and another thrown downward at 6.2 m/s. What is the relative velocity o

erastova [34]

The correct answer is
C) -10.7 m/s

In fact, the first rock is moving upward with velocity +4.5 m/s, while the second rock is moving downward with velocity -6.2 m/s, with respect to a fixed reference frame. In the reference frame of the first rock, instead, the second rock is moving with velocity equal to its velocity in the fixed frame minus the velocity of the reference frame of the first rock:
 $v=-6.2 m/s -(+4.5 m/s) = -10.7 m/s$

Answer:

14J

20000J

200J

Explanation:

formula :W=FS

W:work done

F:force (N)

S:displacement moved in direction of force (m)

1) 20N×0.7m

=14J

2) 400N×50m

= 20000J

3) 10N×20m

=200J

In a simple electric circuit, Ohm's law states that V=IRV=IR, where V is the voltage in volts, I is the current in amperes, and

VMariaS [17]

To solve this problem, apply the concepts given from Ohm's Law. From there we will obtain the derivative of the function with respect to time and with the previously given values we will proceed to find the change in current as a function of the derivative

$V = IR$
