Apply a large force over a short time
Answer:
Total Resistance = 20 ohms
Explanation:
1/Rt = 1/R1 + 1/R2
1/Rt = 1/40 + 1/40
1/Rt = 1/20
Rt = 20
hope it helps!
Answer:
Downwards
Explanation:
Using Fleming's right hand rule, where the middle finger represents the negative charge moving in the south to north direction, the fore finger represents the magnetic field which points in the east to west direction.
If we are to follow this orientation and place the thumb, middle finger and fore-finger at right angles to each other, the thumb represents the direction of the magnetic force on the charge.
In this case, the magnetic force points downwards after setting the other orientations of the magnetic field and the negative charge's direction.
Answer:(b)
Explanation:
Given
Electric current flowing through the horizontal wire towards the observer's face.
The direction of the magnetic field is given by the right-hand thumb rule, i.e. place the thumb in the direction of current and the wrapping of fingers will give the direction of the magnetic field
the direction of the magnetic field will be counterclockwise as observed by an observer.
The gravitational force between two objects may be calculated by the equation,
F = G x (m1 x m2) / d²
where G is universal gravitational constant, m1 and m2 are the masses of two bodies and d is the distance between them. Substituting the known values,
9.20 x 10^-9 = (6.673 x 10^-11) (5.01 kg x m2) / (0.192m)²
The value of m2 is approximately 1.01 kg.
