Answer:
The correct answer is "0.32 mL".
Explanation:
The given values are:
Density of gold bar,
d = 19.3 g/mL
Mass of gold bar,
m = 6.3 grams
Now,
The volume will be:
⇒
or,
⇒
On substituting the values, we get
⇒
⇒
Answer:
-26 m/s.
Explanation:
Hello,
In this case, since the vertical initial velocity is 26 m/s and the vertical final velocity is 0 m/s at P, we compute the time to reach P:
With which we compute the maximum height:
Therefore, the final velocity until the floor, assuming P as the starting point (Voy=0m/s), turns out:
Which is clearly negative since it the projectile is moving downwards the starting point.
Regards.
Answer:
Explanation:
Given
Current in the first wire
Current in the second wire
wires are apart
Force per unit length between the current-carrying wires is
Force exerted by the wires is the same
Put the values
This force will be repulsive in nature as the current is flowing opposite
