Answer:
12 ohms
Explanation:
Ohm's Law tells the relationship between voltage, current, and resistance.
It can be written in three different ways, depending on which ones you know,
and which one you want to find.
Here's the one we need:
Resistance = (voltage) divided by (current)
= (120 V) / (10 Amp)
= 12 ohms .
Acceleration due to gravity is about 9.8 m/s²
So after every second, the speed increase by 9.8 m/s
After 1 second, the object would fall at a speed of 9.8 m/s
After 2 seconds the object would fall at a speed of 19.6 m/s
So after 4 seconds, the object is going to be at a speed of:
9.8 x 4 = 39.2 m/s

<u>Answer</u>
39.2 m/s
Answer:
To avoid slipping while playing badminton or to increase friction between the shoes and the badminton court or to enhance the grip.
Explanation:
As the question is general so I will try answer it generally.
As badminton court is usually slippery and flat with no or very little friction and while playing badminton, players have to move very fast from place to place.
So, in order to effectively move faster to take the difficult shots with accuracy badminton players increase the friction between their shoes and the badminton court by shuffling resin to their shoes. It helps to enhance the grip.
Answer: Truck 2, because it has a larger mass than truck 1 (and the same velocity)
Explanation:
We can write the kinetic energy of an object with mass M and velocity V as:
K = (M/2)*V^2
Let's calculate the kinetic energy for each truck:
Now, we can see that both trucks move at the same velocity, but truck 1 has a mass of 5000 pounds, while truck 2 has also a mass of 5000 pounds and an extra of 900 pounds.
Then the total mass of truck 2 is 5000 pounds + 900 pounds = 5900 pounds.
Then both trucks have the same velocity, and truck 2 has a larger mass than truck 1, this implies that truck 2 will have a larger kinetic energy than truck 1.
In this situation, both of the vehicles turn towards starboard.
By turning to the starboard, or right, side, the vehicles are able to avoid collision. Because waterways are not marked in a manner like roads are, it is necessary to place such conventions of turning in situations where vehicles approach one another head on. If a convention was not in place, the risk of collision would be many times greater. For example, the motorboat operator may turn left, while the PWC operator turns right, resulting in a collision.
