Answer:

4.0 Kg

Explanation:

From the question given above, the following data were obtained:

Velocity (v) = 48 m/s

Kinetic energy (KE) = 4632 J

Mass (m) =?

Kinetic energy can be defined as the energy possess by a moving object. Mathematically, it is expressed as:

KE = ½mv²

Where

KE => kinetic energy

m => mass of object

v => velocity

With the above formula, we can obtain the mass of the object as follow:

Velocity (v) = 48 m/s

Kinetic energy (KE) = 4632 J

Mass (m) =?

KE = ½mv²

4632 = ½ × m × 48²

4632 = ½ × m × 2304

4632 = m × 1152

Divide both side by 1152

m = 4632 / 1152

m = 4.0 Kg

Therefore, the mass of the object is 4.0 Kg

How many minutes of daylight do we gain after winter solstice
serg [7]

Answer:

Depends on which hemisphere you are belong to and how much distance you are away from Ecuador.

Explanation:

Minutes of daylight is equal on everywhere only on the equinox days (21 March and 23 September). On other days it depends on the place that you are belong to. On winter solstice, places on Ecuador have 12 hours daylight. North side of Ecuador have less, south side of Ecuador have more hour of daylight.

This dude was sitting in the chair. Someone pulls the chair out from under him. He does not move in the direction of the chair.
Oksanka [162]

Answer:

This shows inertia because inertia is an object's resistance to change in motion. When the person (imma call them a she) who pulled the chair from under the guy did that, the chair was the one affected by the force of the girl, not the guy. The guy continued heading in the direction he was originally going, which was down.

At least, that's about how I would answer this question.

1. A 3.0 kg mass is tied to a rope and swung in a horizontal circle. If the velocity of the mass is 4.0 ms and
saul85 [17]

10.67m/s²

32N

Explanation:

Given parameters:

Mass of the body = 3kg

velocity of the mass = 4m/s

radius of circle = 0.75m

Unknown:

centripetal acceleration = ?

centripetal force = ?

Solution:

The centripetal force is the force that keeps a radial body in its circular motion. It is directed inward:

   Centripetal acceleration  = \frac{v^{2} }{r}

   v is the velocity of the body

    r is the radius of the circle

  putting in the parameters:

   Centripetal acceleration = \frac{4^{2} }{0.75}

    Centripetal acceleration = 10.67m/s²

Centripetal force = m  \frac{v^{2} }{r}

          m is the mass

 Centripetal force = mass x centripetal acceleration

                              = 3 x 10.67

                              = 32N

Assignment: Can you identify various forces and instances in which electrostatic and magnetic forces occur​
serg [7]

Answer:

Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron. Electric forces exist among stationary electric charges; both electric and magnetic forces exist among moving electric charges. The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.
