Answer:
Tension, T = 0.1429 N
Explanation:
Given that,
Mass of the rock, m = 0.0450 kg
Radius of the circle, r = 0.580 m
Angular speed,
The tension in the string is balanced by the centripetal force acting on it. It is given by :
Since,
T = 0.1429 N
So, the tension in the string is 0.1429 N. Hence, this is the required solution.
Answer:
c) current
Explanation:
Ohm's law states that the current I flowing through a conductor of resistance R is directly proportional to the voltage or potential difference V applied across its terminals provided that the temperature and other necessary conditions remain constant.
Mathematically this law can be written as follows;
When we make R the subject of formula from equation (1), we get the following;
Answer:
More force
Explanation:
Object A has more mass than object B
For object A to accelerate at the same rate as object B, it will need more force.
According to Newton's second law of motion "the net force on a body is the product of its mass and acceleration".
Net force = mass x acceleration
Now, if a body has more mass and needs to accelerate at the same rate as another one with a lower mass, the force on it must be increased.
Peer mediation is problem solving by youth with youth. It is a process by which two or more students involved in a dispute meet in a private, safe and confidential setting to work out problems with the assistance of a trained student mediator.
