joja [24]

Answer:

Option A

Up

Explanation:

we can determine the direction of the angular velocity of a rotaing body by using the right hand rule.

The right hand rule says that if you hold the axis with your right hand and rotate the fingers in the direction of motion of the rotating body then your thumb will point the direction of the angular velocity.

Following this, curving the fingers in such a way that they depict motion from the east to north, we can see that our thumb will point upwards. This makes the direction of the angular velocity at that point in time to be up

2) A sprig with a length of 15 cm and stores 110 J of potential energy when stretched to a new
Alik [6]

Answer:

94.28 cm

Explanation:

The formula for elastic potential energy is given as;

PEel = 1/2 *k*x² where x is the displacement, k is the spring constant

Given

PEel = 110 J, k= 350 N/m  then find x

PEel = 1/2 *k*x²

110 = 1/2 * 350 * x²

110 = 175 x²

110/175 = x²

0.6286=x²

√0.6286 =x

0.7928 m = x

79.28 cm = x

New length of spring = 15 cm + 79.28 cm = 94.28 cm

An empty water tank has a rectangular base with side lengths of 1.2 m and 2.3 m. The weight of the tank applies a pressure of 35
LekaFEV [45]

Answer:

Weight = 966 Newton.

Explanation:

Given the following data;

Length = 1.2 m

Width = 2.3 m

Pressure = 350 Pa

To find the weight of the tank;

We know that weight is the force of gravity acting on an object multiplied by its mass.

Weight = mg = force

Hence, we would determine the force using the parameters that were given.

But we would first determine the area of the rectangular tank.

Area of rectangle, A = length * width

A = 1.2 * 2.3

A = 2.76 m²

Mathematically, pressure is given by the formula;

Pressure = force/area

Force = pressure * area

Substituting into the formula, we have;

Force = 2.76 * 350

Force = 966 Newton

Therefore, the weight of the tank is 966 Newton.
