Can you explain this a bit more I don’t quite understand
Answer: If you slide a hockey puck on ice, eventually it will stop, because of friction on the ice. It will also stop if it hits something, like a player's stick or a goalpost.
Explanation:
The equivalent resistance of several resistors connected in series is
the sum of their individual values.
Four 75-ohm resistors connected in series are electrically equivalent
to a single resistor of 300 ohms.
The battery voltage doesn't matter. In fact, it doesn't matter whether the
resistors are anywhere near a battery or not. They could just as well still
be in the little Radio Shack envelope on the top shelf of the storage room.
If they're connected in series, then they're still electrically equivalent to a
single 300-ohm resistor.
Answer:
The diameter is 0.378 ft.
Explanation:
Given that,
Mass of shot = 12 lb
Density of fresh water = 62.4 lb/ft
Specific gravity = 6.8
We need to calculate the volume of shot

The density of shot is
Using formula of density

Put the value into the formula

We need to calculate the radius
Using formula of specific gravity

Put the value into the formula





The diameter will be



Hence, The diameter is 0.378 ft.
