Explanation:
total answer is 119 km
this is the answer for the question
C
The potential energy is mgh, she knows the mass, she needs the acceleration due to gravity and the height of the ball
I think its C building a barrier wall
Answer:
The electrical resistance of a circuit component or device is defined as the ratio of the voltage applied to the electric current which flows through it: If the resistance is constant over a considerable range of voltage, then Ohm's law, I = V/R, can be used to predict the behavior of the material.
Explanation:
Btw i had a hard time answering the question because you but <u>Ristor </u> and its spelt Resistor
Answer:
a)
b)
Explanation:
From the exercise we know initial velocity, initial height
º
a) The range of the stone is defined by how far does it goes. From the theory of <u><em>free falling objects</em></u>, we have:
The stone strike the water at y=0
Solving for t, using the quadratic formula
or
Since time can't be negative, the answer is t=3.06s
Now, we can calculate the <u>range of the stone</u>
b) We can calculate the <u>velocity</u> were the stone strike the water using the following formula
The negative sign indicates that the stone is going down
