A softball player leaves the batters box, overruns first base by 3.0 meters, and then returns to first base. Compared to the total distance traveled by the player, how much smaller or larger is the magnitude of the players total displacement from the batters box?

Explanation:

mass - 2kg

energy - 16 j

2

k.e- 1/2mv

2

16j=1/2×2×v

2

16×2/2=v

2

16=v

√16=v

V=4m/s

then momentum =mv

= 2×4

= 8 kgm/s

Answer:The rod touching your hand will have a Negative charge.

Explanation: This phenomenon is described as charging by induction,the other iron rod became charged as a result the repulsion force existing between the positively charged iron rod and the electronic forces around the election sphere. This make it different from the charging done by contact where both iron rods have close contact and electron transfer is achieved through contact. The shows that an electric charge can be persuaded and caused to transfer to another metallic particle without physical contact with the charged metallic particle.

Answer:

The initial neutral rod would be induced with negative charges.

Explanation:

This process is called charging by induction. When you bring the charged rod close to that of the neutral, the charges in it would be redistributed. The positively charged rod attracts the negative charges within the neutral rod and repel like charges. Touching the neutral with hand causes the positive charge to be neutralised due to earthing. Thus the neutral rod has now been charged negatively.

Answer:

A) The acceleration will double

Explanation:

Given the expression according to Newton's second law F = ma where;

F is the force

m is the mass of the object

a is the acceleration

Let the initial force be F1 and acceleration be a1

F1 = ma1...(1)

If the pushing force suddenly doubles if the lawn mover is pushed over a length of grass, the new force F2 = 2F1 and acceleration of force F2 will be a2, since the mass doesn't change;

F2 = ma2

2F1 = ma2...(2)

Dividing equation 2 by 1, we will have;

2F1/F1 = ma2/ma1

2 = a2/a1

a2 = 2a1

This shows that the acceleration doubles if the pushing force doubles since force is directly proportional to the acceleration. Increase in the applied force will lead to equal increase in the acceleration and vice versa

Answer:

(1)

Explanation:

Energy released in this process is given by

here we have

since here mass of two electrons converted into energy so we have

so here energy released is the energy of rest mass energy due to two charges i.e. electrons and positrons

The minimum total energy released when an electron and its antiparticle (positron) annihilate each other is 1.64 x 10⁻¹³ J.

What is the minimum total energy released?

The minimum total energy released when an electron and its antiparticle (positron) annihilate each other is calculated as follows;

E = Δmc²

where;

• m is the mass of the two electrons
• c is speed of light

E = (2 x 9.11 x 10⁻³¹) x (3 x 10⁸)²

E = 1.64 x 10⁻¹³ J

Final answer:

The student's question lacks an image, so a specific model can't be identified. However, a common model of Earth's interior includes four parts: the crust, mantle, outer core, and inner core. Each of these parts have distinct characteristics and they are made up of different materials.

Explanation:

Unfortunately, I'm not able to identify the specific model of Earth's interior based on your question as it doesn't include an image for me to review. However, I can tell you that commonly used models include the crust, mantle, outer core, and inner core model, based on our current understanding of geology. The crust is the surface layer, followed by the mantle which is the largest part of Earth's interior. Below the mantle are the outer core and the inner core, which are primarily made up of iron and nickel and exhibit different physical properties.
