Explanation:
We know that for the plant;
Tall is represented by T
Short is represented t
Phenotypically, TT and Tt have the same expression.
The phenotype of an organism denotes the observable feature it possesses. Although determined by the genetic composition but the environment plays a very important role in its expression.
The genotype is the genetic make up of an organism. TT and Tt denotes the genes that occupy positions in the nucleus of the cell.
Both TT and Tt shows that the organism is tall. t is short and recessive.

if the amount of work done remains constant but occurs over less time how does this affect the amount of power exerted?
Answer:
The amount of power will be increased.
Explanation:
If the work remains constant but the time is reduced the power increases. Since power is defined as the relationship between work overtime. By means of the following equation, we can see this relationship.
[tex]P=W/t[/tex]
where:
P = power [Watts]
W = work [J] (units of joules)
t = time [s]
Let's assume with an example the above written.
If we have an electric motor that exerts a work of 950 [J], and the time used is 5 [s], the power is:
[tex]P = 950/5\\P = 190 [W][/tex]
Now if we want to accelerate the work done and use 2 seconds for the time, we will have:
[tex]P=950/2\\P=475 [W][/tex]
We want to see how maintaining the work constant but reducing the time in which it occurs affects the power. We will see that the power increases.
We define power as the amount of work done per unit of time.
So we can compute power as the quotient between the work done and the time in which it is done.
So, if we reduce the time in which the work is done, then the denominator is smaller, thus, the power will be larger.
This means that maintaining the work constant, and reducing the time in which it is done, increases the amount of power exerted.

A man is standing on the edge of a 20.0 m high cliff. He throws a rock horizontally with an initial velocity of 10.0 m/s.
a. How long does it take to reach the ground?
b. How far does the rock land from the base of the cliff?
Answer:
a. The rock takes 2.02 seconds to hit the ground
b. The rock lands at 20,2 m from the base of the cliff
Explanation:
Horizontal motion occurs when an object is thrown horizontally with an initial speed v from a height h above the ground. When it happens, the object moves through a curved path determined by gravity until it hits the ground.
The time taken by the object to hit the ground is calculated by:
[tex]\displaystyle t=\sqrt{\frac{2h}{g}}[/tex]
The range is defined as the maximum horizontal distance traveled by the object and it can be calculated as follows:
[tex]\displaystyle d=v.t[/tex]
The man is standing on the edge of the h=20 m cliff and throws a rock with a horizontal speed of v=10 m/s.

convert one mean solar day into second
Answer:
86400 seconds
Explanation:
To convert a mean solar day to second :
Number of hours in a solar day = 24 hours
Number of minutes per hour = 60 minutes
Number of seconds per minute = 60 minutes
Hence, the number of seconds in a solar day is :
(Number of hours in a solar day * number of minutes in an hour * number of seconds in a minute)
(24 * 60 * 60) seconds = 86400 seconds
Hence, 1 mean solar day = 86400 seconds

How long does it take the lava bomb to reach its maximum height? Answer with three significant digits and the correct unit. A small volcano's steam pressure belches vertically upward a lava bomb from an initial height of 64.4 m and with an initial upward velocity of 31.4 m/s. Remember gravity's acceleration near earth is g = 9.8 m/s2 down.
Answer:
The time taken to reach the maximum height is 3.20 seconds
Explanation:
The given parameters are;
The initial height from which the volcano erupts the lava bomb = 64.4 m
The initial upward velocity of the lava bomb = 31.4 m/s
The acceleration due to gravity, g = 9.8 m/s²
The time it takes the lava bomb to reach its maximum height, t, is given by the following kinematic equation as follows;
v = u - g·t
Where;
v = The final velocity = 0 m/s at maximum height
u = The initial velocity = 31.4 m/s
g = The acceleration due to gravity = 9.8 m/s²
t = The time taken to reach the maximum height
Substituting the values gives;
0 = 31.4 - 9.8 × t
∴ 31.4 = 9.8 × t
t = 31.4/9.8 ≈ 3.204
The time taken to reach the maximum height rounded to three significant figures = t ≈ 3.20 seconds
Which celestial body would have the strongest gravitational pull on a satellite orbiting 100 km above its surface? Explain your answer.
Answer:
Jupiter
Explanation:
Since the mass of Jupiter is the greatest from the given choices, it will exert the most force on any object orbiting 100km above its surface.
This is compliance with the Newton's law of universal gravitation which states that "the force of attraction between two bodies is directly proportional to the magnitude of their masses and inversely proportional to the distances between them".
Therefore, the more the masses of two bodies, the higher the gravitational attractionSince the distance is the same, the planet with the greater mass will exert the most force on the satellite.Answer:
Sample Response: Jupiter would have the strongest gravitational pull on a satellite orbiting above its surface because gravity is directly proportional to mass and Jupiter is the most massive planet.

a truck of mass 200kg rests on an inclined plane hindered from rolling down the surface by a storing sprint whose force constant is 10^6N/M.neglecting friction,how much work does the truck do on the spring?
Answer:
1.92 J
Explanation:
From the question given above, the following data were obtained:
Mass (m) = 200 Kg
Spring constant (K) = 10⁶ N/m
Workdone =?
Next, we shall determine the force exerted on the spring. This can be obtained as follow:
Mass (m) = 200 Kg
Acceleration due to gravity (g) = 9.8 m/s²
Force (F) =?
F = m × g
F = 200 × 9.8
F = 1960 N
Next we shall determine the extent to which the spring stretches. This can be obtained as follow:
Spring constant (K) = 10⁶ N/m
Force (F) = 1960 N
Extention (e) =?
F = Ke
1960 = 10⁶ × e
Divide both side by 10⁶
e = 1960 / 10⁶
e = 0.00196 m
Finally, we shall determine energy (Workdone) on the spring as follow:
Spring constant (K) = 10⁶ N/m
Extention (e) = 0.00196 m
Energy (E) =?
E = ½Ke²
E = ½ × 10⁶ × (0.00196)²
E = 1.92 J
Therefore, the Workdone on the spring is 1.92 J

Write the newtons formula for the velocity of sound in air .how did Laplace correct this formula ?
Answer:
1: v = √E/ρ where E is the elasticity and ρ is the density. Newton's assumed that sound wave travel in air under isothermal condition
2: He corrected Newton's formula by assuming that, there is no heat exchange takes place as the compression and rarefaction takes place very fast. Thus, the temperature does not remain constant and the propagation of the sound wave in air is an adiabatic process.
Marc was told his dinner would be ready at 18:00. He left his house at 12:00 and travelled in his car at an average speed of 45mph to his mum's house 300 miles away. Did Marc make it home in time for dinner
Answer:
No
Explanation:
No, Marc did not make it on time for dinner.
The time duration between 12:00 and 18:00 is 6 hours.
Total distance that needs to be covered from his house to his mum's house and back = 300 miles x 2 = 600 miles
Time that would be needed to cover 600 miles to his mum's house at an average speed of 45 mph = distance/speed
= 600/45
= 13.33 hours
The required time to cover the distance by Marc is approximately 13.33 hours. If he leaves the house by 12:00, he will definitely not get back 6 hours after. Hence, he could not have made it for dinner.
How does an increase in thermal energy affect the particle motion in each state of matter?
Answer:
Explanation:
A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures. Individual particles in liquids and gases have no fixed positions and move chaotically.
deduce the relation between kwh and joule define 1 watt
Explanation:
We know that kWh is a commercial unit of energy.
Also, 1 Joule = 1 watt × 1 seconds
[tex]1\ kWh=1kW \times 1\ h[/tex]
Since ,1 h = 3600 s and 1kW = 1000 W
[tex]1\ kWh=1000\ W \times 3600\ s\\\\1\ kWh = 36\times 10^5\ W-s\\\\1\ kWh=36\times 10^5\ J[/tex]
So, the relation is : [tex]1\ kWh=36\times 10^5\ J[/tex]
1 watt is defined as the power of an appliance when the energy is transferred at a rate of 1 Joule per second.
