WHICH TYPES OF ENERGY IS HAPPENING

Answer:

c.) magnetosphere

Explanation:

I think is C

In projectile horizontal distance is given by :

[tex]h = \dfrac{u^2sin^ 2\theta}{2g}[/tex]

Putting all given values, we get :

[tex]h = \dfrac{u^2sin^ 2\theta}{2g}\\\\h=\dfrac{16^2\times sin^2 \ 55.3^o}{2\times 9.8}\\\\h=13.1\ m[/tex]

Therefore, maximum height of football is 13.1 m.

Hence, this is the required solution.

Answer:

The Sun shines by turning hydrogen into helium in its core.

Explanation:

This process is called nuclear fusion. Fusion happens when lighter elements are forced together to become heavier elements. When this happens, a tremendous amount of energy is created.

That`s is the answer, just check

Answer:

Explanation:

Given

v = 10.22m/s

u = 9.78m/s

S = 200m

Using the equation of motion'

v² = u² + 2aS

v is the final velocity

u is the initial velocity

a is the acceleration

S is the displacement

Substitute the given parameters into the formula:

10.22² = 9.78² + 2a(200)

104.4484 = 95.6484 + 400a

400a = 104.4484 -95.6484

400a = 8.8

a = 8.8/400

a = 0.022m/s²

Hence the magnitude of his acceleration would have been 0.022m/s²

Answer: The answer is 16Kg

Explanation:If you use the formula for mass, mass=force/acceleration and plug the numbers into the formula, 48/3 you would get

16Kg

Mechanical energy = Kinetic Energy + Potential Energy

Kinetic energy = 1/2 * m * v² = 1/2 * 3.5 * (10)²

=> Kinetic energy = 175 J

Potential energy = m * g * h = 3.5 * 10 * 3 = 105 J

Hence,

Mechanical energy = Kinetic Energy + Potential Energy

= 175 J + 105 J

= 280 J

Taking into account the potencial, kinetic and mechanical energy, the total mechanical energy is 278.005 J.

Potential energy refers to the position that a mass occupies in space and its magnitude is directly proportional to the height at which the object is, with respect to a reference position, to the mass of the object and to gravity:

Ep = m×g×h

On the other hand, kinetic energy manifests itself when bodies move and is associated with speed. The kinetic energy of a body depends on its mass and the square of its speed:

Ec = [tex]\frac{1}{2}[/tex]×m×v²

The mechanical energy of a body is the capacity it has to carry out mechanical work, that is, to produce a movement due to causes of mechanical origin, such as its position or its speed.

The mechanical energy of a body is the sum of its kinetic energy and its potential energy:

Em = Ep + Ec

Where

Then:

Em= m×g×h + [tex]\frac{1}{2}[/tex]×m×v²

The Principle of conservation of mechanical energy indicates that, in the absence of friction and without the intervention of any external work, the sum of the kinetic and potential energies remains constant, that is, the mechanical energy of a body remains constant throughout the movement. if no friction force acts.

In this case, you know that:

Complying with the Principle of Conservation of Mechanical Energy and replacing in the expression of mechanical energy:

Em= 3.5 kg×9.81 [tex]\frac{m}{s^{2} }[/tex]×3 m + [tex]\frac{1}{2}[/tex]×3.5 kg×(10 [tex]\frac{m}{s}[/tex])²

Solving:

Em=103.005 J + 175 J

Em= 278.005 J

Finally, the total mechanical energy is 278.005 J.

Answer:

The energy an object has due to its motion is called kinetic energy

Explanation:

Factors Affecting Kinetic Energy: the kinetic energy of an object depends on both its speed and its mass.

Answer:

kinetic energy

Explanation:

In physics, the kinetic energy (KE) of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.

Answer:

Electronegative atom will create a stronger negative charge is true.

Explanation:

Given that,

Electronegativity affects the strength of intermolecular forces.

We know that,

Electronegativity :

Electronegativity is a ability of an atom, shared electron to itself.

In periodic table,

When we move left to right in period then the electronegativity increases.

When we move up to down in a group then the electronegativity decreases.

We know that,

The intermolecular forces are dipole-dipole interactions which is the strongest intermolecular force of attraction.

If the electronegativity of atom is more, then the atom gain negative charge.

When the attraction force is more in atoms then the electronegative will be more.

Hence, Electronegative atom will create a stronger negative charge is true.

Steps to determine the specific heat capacity.

1. Place a beaker on a balance and press zero.

2. Now add the oil to the beaker and record the mass of the oil.

3. Read the starting temperature of the oil.

4. Connect a joulemeter to the immersion heater.

5. Time for thirty minutes.

6. Read the number of joules of energy that passed into the immersion heater.

7. Read the final temperature of the oil.

8. Use the following formula to calculate the specific heat capacity.

Explanation:

plz mark as brainliest aswer

Because it takes more force to accelerate a mass, and gravity exerts more force on a greater mass.  So every object winds up with the same acceleration.  

And THAT, of course, says that all objects in the same gravity will pick up the same speed in the same time, and fall the same distance in the same time.

Answer:

It took the projectile 120 s to reach the maximum height.

Explanation:

Given;

maximum height of the projectile, s = 180 km = 180,000 m

initial speed of the projectile, u = 3 km/s = 3000 m/s

final velocity at maximum height, v = 0

Apply the following kinematic equation for average velocity of the projectile;

[tex]s = (\frac{v+u}{2} )t\\\\(v+u)t = 2s\\\\t = \frac{2s}{v+u} \\\\t = \frac{2*180,000}{0+3,000}\\\\ t = 120 \ s[/tex]

Therefore, it took the projectile 120 s to reach the maximum height.

A parallel circuit, is one which the conductors leading into the bulbs are joined together on one side of the bulbs, and the conductors coming out of the bulbs are joined together on the other side of the bulb

The correct arrangement, advantages, lamp and resistance values are;

The reason the above values are correct are as follows:

(i) From the diagram attached, the lamps are arrange in parallel

This is so because, each lamp is directly connected across the terminals of the the voltage source

(ii) The advantages of the bulbs arranges in parallel are;

(iii) The brightness of the lamp is given by the power of the lamp

The lamp with the highest wattage, or power glows the most

Power, P = Voltage, V × Current, I

The power for lamp A, [tex]P_A[/tex] = 60 V × 3 A = 180 W

The power for lamp B, [tex]P_B[/tex] = 60 V × 4 A = 240 W

The power for lamp C, [tex]P_C[/tex] = 60 V × 5 A = 300 W (Brightest)

The power for lamp D, [tex]P_D[/tex] = 60 V × 3 A = 180 W

Therefore, lamp C has the highest power and glows the brightest

(iv) The total resistance is given by the voltage, divided by the total current

Total current, I = 3 A + 4 A + 5 A + 3 A = 15 A

[tex]Total \ resistance, \ R_{tot} = \dfrac{V}{I_{tot}}[/tex]

Therefore;

[tex]Total \ resistance, \ R_{tot} = \dfrac{60 \, V}{15 \, A }}=4 \, \Omega[/tex]

The total resistance, R = 4 Ω

Answer:

A) 6 [g/cm^3]

Explanation:

The volume of a cube is equal to the product of height by width by length, all these dimensions are equal.

V = L*L*L

where:

L = 5 [cm]

V = (5)^3

V = 125 [cm^3]

Density is defined as the relationship between mass and volume.

density = mass/volume

density = 750/125

density = 6 [g/cm^3]
