Answer:

Kinetic energy and potential energy.

Explanation:

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v^2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared. Kinetic energy is usually measured in units of Joules (J); one Joule is equal to 1 kg m^2 / s^2.

The formula for potential energy depends on the force acting on the two objects. For the gravitational force, the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m/s^2 at the surface of the earth) and h is the height in meters. Notice that gravitational potential energy has the same units as kinetic energy, kg m^2/s^2. In fact, all energy has the same units, kg m^2/s^2, and is measured using the unit Joule (J).

Work is also measured with the unit Joule (J).

Explanation:

The maximum height of a object in a projectile trajectory occurs when the vertical component of velocity, vy , equals zero. As the projectile moves upwards it goes against gravity, and therefore the velocity begins to decelerate. ... Once the projectile reaches its maximum height, it begins to accelerate downward.

Answer:

Examples of Newton's third law of motion are ubiquitous in everyday life. For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air. Engineers apply Newton's third law when designing rockets and other projectile devices.

A represents change of state named sublimation.

B represents change of state named evaporation.

C represents change of state named melting.

Sublimation is the straight transition from a solid state of materials to a vapor state upon heating (without becoming liquid).

A process known as evaporation occurs when a liquid turns into a gas below the boiling point. Water turns into a gas when it absorbs heat energy.

The phase transition of a substance from a solid to a liquid state is referred to as melting. This occurrence is known as a phase change, meaning that a substance is changed from one state of matter to another during this process.

Hence, A, B, C represent changes of state named sublimation, evaporation and melting respectively.

Because next to hydrogen symbol 'H' the number 2 is written which tells us the number of hydrogen which are present and also because every water contains 2 hydrogen atoms and 1 oxygen atom.

Answer:

C

Explanation:

2 because if you look closely, there is a two behind the hydrogen. (H20). This means that there are two hydrogen atoms in the molecule.

Answer:

The third option

Explanation:

A and B are true because this can be noticed by just any human. So then you are left with C and D. With these two, D makes more sense. Since when someone gets cold, their blood flow is reduced starting in areas like your fingers, hands, toes and feet. These areas get the coldest since they are the smallest and furthest away from the rest of your body. Also since these areas touch surfaces more than other areas, they will have less heat to transfer.

Blood flow is diverted from muscle tissue to fat. The rapid decomposition fat (adipose) tissue generates heat energy that helps to raise the body's temperature. - This answer is NOT correct.

nervous system is a network of organized cells with the specific purpose of carrying electrochemical inputs from sensory receptors to the location where a response takes place.

A train travels between two stations that are 63 km apart at an average speed of 35 m/s. Time taken by train after leaving the first station and arrive at the second station  1.8 sec.

The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.

time = Distance / speed

= 63/35.

= 1.8 sec

Answer:

[tex]\theta=119.06^{\circ}[/tex]

Explanation:

The vector is :

A = -25i+45j

We need to find the angle between angle A and the positive x-axis. It can be calculated as follows :

[tex]\theta=180^{\circ}-\tan^{-1} (\dfrac{45}{25})\\\\=180-60.94\\\\=119.06^{\circ}[/tex]

So, the angle of vector A with the +x axis is [tex]119.06^{\circ}[/tex].

Answer:

23.67 m

Explanation:

We are given;

Now, formula to get the wavelength is from the wave equation which is;

v = fλ

Where λ is wavelength

Making λ the subject, we have;

λ = v/f

λ = 7.1/0.3

λ = 23.67 m

In a system with a hanging mass and an inextensible wire, the force is proportional to the sino, in the case of small oscillations, approximately the stop angle, this hiss is lost, the calibration for large amplitudes is lost.

Explanation:

In a spring-mass system the restoring force created by the spring is proportional to displacement from the equilibrium position, therefore this watch does not require streamlining as the amplitude of movement increases.

In a system with a hanging mass and an inextensible wire, the force is proportional to the sino, in the case of small oscillations, approximately the stop angle, this hiss is lost, the calibration for large amplitudes is lost.

Answer:

Option D, only on the portion of the Earth facing directly toward the Moon

Explanation:

Tides are caused by the gravitational pull of moon. The part of earth that faces the moon experiences the highest gravitational force and hence the high tides will occur in this regions only. The regions that do not faces the moon experiences low tides. It is the gravity of moon that attracts the ocean water towards itself.

Hence, Option D is correct

Answer:

Spring tide, tide of maximal range, near the time of new and full moon when the Sun and Moon are in syzygy—i.e., aligned with the Earth. ... In either case of syzygy, the tide-producing forces of the Sun and the Moon reinforce each other, and the tidal amplitudes on Earth are at their greatest.

Answer:

When you are running the most important force that you should understand is friction. Friction is a force that opposes movement between two objects, but for runners friction makes you faster. Friction gives you a better and more efficient way to use your energy into speed.

The reaction force provided by the tracks as the runners press their feet against the track provides the maximum force.

The newton's third law of motion states that every action has a equal and opposite reaction

Given is to find what force allow the runners to move.

The reaction force provided by the tracks just before the runners start running as they press their feet against the track provides the maximum force.

Therefore, the reaction force provided by the tracks as the runners press their feet against the track provides the maximum force.

Answer:

Tarzan will be moving at 7.4 m/s.

Explanation:

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

Height (h) of cliff = 2.8 m

Initial velocity (u) = 0 m/s

Final velocity (v) =?

NOTE: Acceleration due to gravity (g) = 9.8 m/s²

Finally, we shall determine how fast (i.e final velocity) Tarzan will be moving at the bottom. This can be obtained as follow:

v² = u² + 2gh

v² = 0² + (2 × 9.8 × 2.8)

v² = 0 + 54.88

v² = 54.88

Take the square root of both side

v = √54.88

v = 7.4 m/s

Therefore, Tarzan will be moving at 7.4 m/s at the bottom.

Answer:

Explanation:

The cannonball goes a horizontal  distance of 275 m . It travels a vertical distance of 100 m

Time taken to cover vertical distance =  t ,

Initial velocity u = 0

distance s = 100 m

acceleration a = 9.8 m /s²

s = ut + 1/2 g t²

100 = .5 x 9.8 x t²

t = 4.51 s

During this time it travels horizontally also uniformly so

horizontal velocity Vx = horizontal displacement / time

= 275 / 4.51 = 60.97 m /s

Vertical velocity Vy

Vy = u + gt

= 0 + 9.8 x 4.51

= 44.2 m /s

Resultant velocity

V = √ ( 44.2² + 60.97² )

= √ ( 1953.64 + 3717.34 )

= 75.3 m /s

Angle with horizontal Ф

TanФ = Vy / Vx

= 44.2 / 60.97

= .725

Ф = 36⁰ .
