Explanation:

Kinetic Energy

Is the type of energy of an object due to its state of motion. It's proportional to the square of the speed.

The formula to calculate the kinetic energy is:

[tex]\displaystyle K=\frac{1}{2}mv^2[/tex]

Where:

m = mass

v = speed

The kinetic energy is often expressed in Joules (J)

We are given the mass of a fly m=0.638 g and we need to calculate its speed in order to have a kinetic energy of 74354.5 J.

Converting:

m=0.638 g /1000 = 0.000638 kg

To find the speed, we solve the formula for v:

[tex]\displaystyle v=\sqrt{\frac{2K}{m}}[/tex]

[tex]\displaystyle v=\sqrt{\frac{2K}{m}}[/tex]

Substituting:

[tex]\displaystyle v=\sqrt{\frac{2*74354.5}{0.000638}}[/tex]

v = 15,267 m/s

(The fly should move faster than a rocket)

The solubility of the salt. : 24 g/100 g solvent(water)

Given

48 gram of a salt in 200 gram of water at 35°C

Required

The solubility of the salt.​

Solution

Solubility : the amount of a substance that can be dissolved in a solvent

Can be formulated(for 100 g solution)⇒grams solute per 100 g of solvent(100 ml water)

[tex]\tt solubility=\dfrac{mass~solute}{mass~solvent}\times 100[/tex]

Input the value :

[tex]\tt solubilty=\dfrac{48~}{200~g}\times 100=24~g[/tex]

Answer:

The maximum height is determined by the initial vertical velocity. Since steeper launch angles have a larger vertical velocity component, increasing the launch angle increases the maximum height.

Answer:

2.5m/s²

Explanation:

Given the following:

Initial velocity u = 0m/s

Final velocity v = 20m/s

Time t = 4s

Required

average acceleration over this time in time interval​

Using the equation of motion

v = u + at

10 = 0 + a(4)

10 = 4a

a = 10/4

a = 2.5m/s²

Hence its average acceleration over this time in time interval​ is 2.5m/s²

Answer:

Compressions

Explanation:

A longitudinal wave is a wave in which the direction of propagation of the wave and the direction of the displacement of the particles of the wave are parallel.

As the wave propagates, the particles do not move, but, oscillate back and forth about their equilibrium position, and there are thus regions of high pressure called compressions and regions of low pressure called rarefactions.

The amplitude is thus the distance between successive compressions.

Answer:

μ = 0.391

Explanation:

The friction force is defined as the product of the coefficient of friction by the normal force. In this way, we have the following equation.

F = μ*N

Where:

F = friction force = 403 [N]

μ = static coefficient

N = Normal force [N]

And the normal force of a body lying on a horizontal surface can be calculated by means of the product of mass by gravitational acceleration.

[tex]N=m*g\\N=105[kg]\\g=9.81 [m/s^{2} ]\\N=105*9.81\\N=1030.05[N][/tex]

Now we can clear the  static coefficient

[tex]403=u*1030.05\\u=0.391[/tex]

Answer:

180Ns

Explanation:

Given parameters:

Force applied  = 90N

Velocity  = 15m/s

Time taken  = 2s

Unknown:

Impulse applied to the cart  = ?

Solution:

The impulse is effect of force acting on a body through time.

 It is mathematically expressed as;

 Impulse  = Force x time

 So;

 Impulse on the car  = 90 x 2  = 180Ns

Answer:

80.12J

Explanation:

Given parameters:

Mass of the bowling ball = 7.3kg

Height of the storage rack  = 1.12m

Unknown:

Energy the ball would have exerted  = ?

Solution:

To solve this problem, the potential energy is the best parameter to use.

Potential energy is the energy due to the position of a body. It is expressed as:

    Potential energy  = mass x gravity x height

So;

   Potential energy = 7.3 x 9.8 x 1.12 = 80.12J

Answer:

If a car is moving at a constant velocity of 10 m/s, there will be no change in the velocity per time.

Acceleration is the rate of change of velocity

Acceleration=(Final velocity-Initial velocity)/Time

Acceleration=(10m/s-10m/s)/Time= 0 m/s²

Answer:

1470J

Explanation:

Given parameters:

Mass of the block  = 30kg

Height  = 5m

Unknown:

Gravitational potential energy  = ?

Solution:

The Gravitational potential energy of body is due to its position above the ground level.

 Gravitational potential energy  = mass x acceleration due to gravity x height

So;

Gravitational potential energy  = 30 x 9.8 x 5 = 1470J

Explanation:

Peppered moths use the adaptation of camouflage as protection from predators. They may have a variety of colors or shades, but before the Industrial Revolution, they were typically white with black speckles. The Industrial Revolution in the 1880s introduced large-scale pollution into the environment. The pollution resulted in widespread, dark-colored staining of buildings and trees.  Which is the most likely effect of the Industrial Revolution on peppered moths in cities?

The correct answer would be that the population of light-colored moths decreased and the population of dark-colored moths increased.

Organisms evolve so as to adapt to changes in their environment for continued survival. Peppered moths served as preys for birds and one of the adaptations to survive is adaptive coloration. In an environment characterized by dark-colored  buildings and trees, light-colored moths would easily be picked out by predating birds, unlike dark-colored ones.

Hence, more of the light-colored moths would be picked out by predators while the dark-colored ones would be able to reproduce and multiply at a faster rate than their counterparts. The implication is that there would be a decrease in the population of light-colored moths and an increase in the population of the dark-colored ones.

The average velocity of the horse at the given displacement is 2.07 m/s.

The given parameters:

The average velocity of the horse is determined as the ratio of the total displacement to time of motion.

[tex]v = \frac{\Delta x}{\Delta t} \\\\v = \frac{x_2 - x_1 }{t} \\\\v = \frac{15 - (-14)}{14} \\\\v = \frac{15 + 14}{14} \\\\v = \frac{29}{14} \\\\v = 2.07 \ m/s[/tex]

Thus, the average velocity of the horse at the given displacement is 2.07 m/s.
