<em>Power = (voltage) x (current)</em>
We don't actually know what power<em> rating</em> may be marked on the bulb or the package it comes in, but the power it actually consumes and dissipates, when connected to a 15V battery, is . . .
Power = (15 V) x (3.0 A) = <em>45 watts</em>
Answer:
A=Gas
B= Solid
C=Liquid
Explanation:
A gas has the particles dispersed everywhere
so A is the gas
Liquid and Solid have them more close together
but the solid has them in some order
so as you can see
B is solid
and
C is liquid
Answer:3500N
Explanation:
mass=700kg
acceleration=5m/s^2
Force=mass x acceleration
Force=700 x 5
Force=3500
Force=3500N
Answer:
The correct option is D
Explanation:
From the question we are told that
The speed of the first charge is
This is because it is at rest
The speed of the second charge is
Generally the force exerted by a magnetic field on a charge is mathematically represented as
Now looking at this above equation we can see that can only be maximum at and this only obtained when the direction of the charge (i.e its velocity ) is perpendicular to the direction of the magnetic field
so the correct option for this question is D
Answer:
The value is
Explanation:
From the question we are told that
The mass of each sphere is
The length of the string is
The angle of with the vertical is
The acceleration due to gravity is
Generally the force acting between the forces is mathematically represented as
=>
Generally from Pythagoras theorem the radius of the circular curve created by the force is
=>
=>
=>
=>
=>
