Bru this was a challenge......but

Force = Mass × Acceleration

Mass = 2.5 kg

Acceleration = 4 m/s^2

Force = 2.5 × 4

Force = 10 N

The energy from the sun caused water to heat up and evaporate.

Answer:

V/Ve = 1.1

Explanation:

The formula to find the escape velocity of an object at a distance from Earth's Surface is given as follows:

Ve = √[2GM/R]

where,

Ve = escape velocity = ?

G = Universal Gravitational  Constant = 6.67 x 10⁻¹¹ N.m²/kg²

M = Mass of Earth = 5.97 x 10²⁴ kg

R = Radius of Earth = 6.37 x 10⁶ m

Therefore,

Ve = √[2(6.67 x 10⁻¹¹ N.m²/kg²)(5.97 x 10²⁴ kg)/(6.37 x 10⁶ m)]

Ve = 11.2 x 10³ m/s = 11.2 km/s

Hence, the ratio will be:

V/Ve = (12.3 km/s)/(11.2 km/s)

V/Ve = 1.1

Answer:

it is attracted to negative pole

A copper wire will get attracted to negative pole of magnetic field when it

is moved across it

The copper wire has free electrons in it which when moved across the

magnetic field will result in the movement of the electrons to the negative

pole of the magnetic field.

This is because unlike poles attract and like poles repel. Copper is a metal

and positively charged and so it gets attracted to the negative pole during

electron flow.

Answer:

cardiovascular endurance is alot like mostly running

Answer:

0 (zero) Joules

Explanation:

If the displacement is 0 (zero) meters, then the work is zero, since it is defined as the product of the force exerted times the displacement that occurred in the same direction of the force.

If the displacement is zero, the product becomes zero as well.

Answer:

He was 0.4781 s in air.

Explanation:

This question is on an object launched horizontally with zero angle and at a height H.

The formula to apply is ;

[tex]T=\sqrt{\frac{2H}{g} }[/tex]

where ;

T=time of flight = ?

H= height of the object was launched = 1.12 m

T= √2*1.12/9.8

T=√0.22857

T= 0.4781 seconds

Answer: e. P/2

Explanation:

For ideal gases, we have the relation:

P*V = n*R*T

where:

n =  number of mols

R = Gas constant

T = temperature

V = volume

P = pressure.

We know that for sample A, we have n moles, a temperature T and a volume V, then the pressure of this sample will be:

Pa = (n*R*T)/V.

For sample B, we have:

n/2 moles, temperature T/2 and a volume V/2, then the pressure will be:

Pb = (n/2)*R*(T/2)*(2/V) = (n*R*T/V)*(2/4)

and:

(n*R*T/V) = Pa

Then we can replace it and we get:

Pb = (n*R*T/V)*(2/4) = Pa*(2/4) = Pa*(1/2) = Pa/2.

Then the correct option is e.

Answer:

8 kg*m/s and 2m/s

Explanation:

momentum is mass times velocity. since the velocity changes by 2 m/s. you just take the difference from final velocity to beginning velocity.

4kg*12m/s = 48 kg*m/s

4kg*10m/s = 40 kg*m/s

48kg*m/s - 40 kg*m/s = 8kg*m/s

Explanation:

they are electropositive have a tendency to give electrons

Answer:

Magnetism is an example of a non-contact or action-at-a-distance force. These are forces which can act on an object without being in physical contact with it. The force of gravity is another example. Thus, gravity will pull a raindrop down to Earth without any tangible physical link between the Earth and the drop.

hope this helps u, sorry if it doesn't.

Answer:

Magnetic force

Explanation:

It would be this because all of th other forces are touching the object to make it move or somhting like that, the only one that makes it move by not touching it would be the magnetic force,

Answer:

Explanation:

A Pythagorean triple consists of three positive integers a, b, and c, such that a2 + b2 = c2. ... The name is derived from the Pythagorean theorem, stating that every right triangle has side lengths satisfying the formula a2 + b2 = c2; thus, Pythagorean triples describe the three integer side lengths of a right triangle.

Answer:

6.9m/s

Explanation:

Given parameters:

Acceleration of the object  = 4m/s²

Distance = from x; 2m to x; 8m

Unknown:

Average velocity  = ?

Solution:

From the given parameters, we use the right motion equation to solve the problem.

   v² = u² + 2aS

v is the final velocity

u is the initial velocity

a is the acceleration

 S is the distance covered

 Distance  = 8m - 2m  = 6m

 Initial velocity  = 0m/s

The final velocity gives us the average velocity in this problem;

       v² = 0² + (2 x 4 x 6) = 48

      v = √48  = 6.9m/s
