Answer:
This is true
Explanation:
This is true because in other To measure the potential difference that is across a circuit, we have to place the device called the voltmeter to be in parallel withe the circuit, so as to get a measurement of the difference in energy from one side of the circuit to the other side. We can also refer to the Potential difference as the voltage and it is measured in volts using a voltmeter
As per Newton's II law we know that
here
F = applied unbalanced force
m = mass of object
a = acceleration of object
now it is given that force F = 50 N North applied on block on earth due to which block will accelerate by 4 m/s^2
so here from above equation
Now we took another situation where block is placed on surface of moon and again force F = 25 N is applied on the block
So we will again use Newton's II law
so block will accelerate on moon by acceleration 2 m/s^2
Answer: 9. 9 times force
8. 7000 N/C directed towards q₂
Explanation:
9.
Let the two charges be and separated by distance r. Then the force of repulsion is given as :
where, k is the Coulomb's constant.
When the magnitude of the charges is tripled: and , the new force of repulsion, force' is:
8.
The electric field is given by:
where q is the charge and r is the distance of the point from the charge where electric field is required to be found.
It is given that,
Electric field due to charge at point a is:
Electric field due to charge at point a is:
Thus, net electric field due to both charges at a is
The force that a moving object has which is dependent on the speed and weight of the object is Momentum
The product of an object's mass and velocity is known as its linear momentum, translational momentum, or simply momentum in Newtonian physics. It has both a magnitude and a direction, making it a vector quantity. When an object has a mass of m and a speed of v, its momentum, p, is equal to ma. Its SI Unit is Kgm/s
The speed of a body is defined as the rate at which the position of a body changes per unit of time. Its SI unit is m/s.
Weight is defined as the amount of force, in general, it's the gravitational force, which acts on the body. It is measured in Kilogram (kg).
