A 30 N rightward force is exerted on a 7 kg object. There is a 3 N force of friction acting on the object. What is the Weight of
IgorLugansk [536]

Answer:

W = 68.6 N

Explanation:

Given that,

Force acting on a right side = 30 N

Mass of the object, m = 7 kg

The force of friction acting on the car = 3 N

We need to find the weight of the object.

The weight of an object is given by :

W = mg

Substitute all the values,

W = 7 × 9.8

W = 68.6 N

So, the weight of the object is 68.6 N.

Find the magnitude of the force that our planet's magnetic field exerts on this wire if it is oriented so that the current in it
laila [671]

Answer: F = 2.1 x 10^-4N

Explanation: Question is incomplete.

The complete question is; A straight, 2.5-m wire carries a typical household current of 1.5 A (in one direction) at a location where the earth’s magnetic field is 0.55 gauss from south to north. Find the magnitude and direction of the force that our planet’s magnetic field exerts on this wire if it is oriented so that the current in it is running (a) from west to east.

Given parameters; l = 2.5m, I = 1.5A, B = 0.55 guass = 0.55 x 10^-4 Tesla , theta = 90 (from West to East), F = ?

F = BILsin(theta)

F = 0.55 x 10^-4 x 1.5 x 2.5 x sin 90

F = 2.1 x 10^-4 N.

According to right hand rule, it's direction is upward.
