Explanation: because it changes the DNA sequence of a gene

Answer:the same

Explanation:their moving at the same speed and collapse

According to Newton's law, the force exerted by the bug and car is equal and opposite. Thus their acceleration decreases as mass increases. Therefore the acceleration of bug will be greater than that of the car.

Acceleration, in physics is the rate of change in velocity. Thus it has the unit m/s². Newton's second law of motion states that the force acting on a moving body is the product of its mass and acceleration.

Hence F=  m a indicates that the acceleration is in inverse proportionality with the mass. Thus a body with greater mass will have smaller acceleration but greater force.

According to third  law of motion, an action have an equal opposite reaction. Thus the force exerted by the bug on the car and the force exerted by the car on bug are equal and opposite where, the bug will have greater acceleration due to its less mass.

Answer:

As the roller coaster goes higher, more potential energy is increased in the roller coaster. Caused by gravity and the roller coaster's position, the potential energy is stored in the roller coaster. For example, this ball is at the top of a hill, where potential energy is at it's highest. Potential energy can be calculated by Potential Energy=Mass X Acceleration X Height.

Explanation:

The factor that impact the amount of potential and kinetic energy should be explained below.

Since the roller coaster should be high which there should be more potential energy and the same should be increased.

Due to the gravity and the position of the roller coaster the potential energy should be stored in the rolar coaster.

Just like when the ball is in the top of the hill when there is high potential energy so in this way it should be impacted.

Answer:

To send a pulse of different speed, change the tension or stretch on the spring

Explanation:

A pulse is a single disturbance of a particle is a medium. The pulse has an amplitude or and a pulse length in the medium. The speed of the pulse is dependent on the amount of strain or tension ( stretch) applied to the medium. The speed also determines the length of the pulse but is unaffected by the or amplitude of the pulse.

Answer:

[tex]\eta_{turbine} = 0.777 = 77.7\%[/tex]

[tex]\eta_{combined} = 0.728 = 72.8\%[/tex]

Explanation:

First we calculate the power input to the turbine. The input power will be equal to the potential energy of water per unit time:

Input Power = [tex]P_{in} = \frac{Work}{Time} = \frac{Potential\ Energy\ of\ Water}{t} \\P_{in} = \frac{(mass)(g)(height)}{Time} = (mass flow rate)(g)(height)\\\\P_{in} = (1500\ kg/s)(9.81\ m/s^2)(70\ m)\\P_{in} = 1.03\ x\ 10^6\ W = 1030\ KW[/tex]

Now, for turbine efficiency:

[tex]\eta_{turbine} = \frac{Mechanical\ Power\ Out}{P_{in}}\\\\\eta_{turbine} = \frac{800\ KW}{1030\ KW}\\\\\eta_{turbine} = 0.777 = 77.7\%[/tex]

for generator efficiency:

[tex]\eta_{generator} = \frac{Power\ Generation}{Mechanical\ Power\ Out}\\\\ \eta_{generator} = \frac{750\ KW}{800\ KW}\\\\\eta_{turbine} = 0.9375 = 93.75\%[/tex]

Now, for combined efficiency:

[tex]\eta_{combined} = \eta_{turbine}\ \eta_{generator}\\\\\eta_{combined} = (0.777)(0.937)\\\eta_{combined} = 0.728 = 72.8\%[/tex]

Answer:

143

Explanation:

Using one of the 3 fundamental equations in physics, y=vo*t+1/2gt^2, we can use this equation to find the total distance that was traveled.

Acceleration due to gravity is always 9.8m/s^2 and time is 5.4s, we also have no initial velocity.

Given this, we can plug in the known variables.

y=0t+1/2*9.8*5^2

simplify,

y=4.9*5.4^2

y=4.9*29.16

y=142.884m which we can round up to 143 meters

Final Answer: 143 meters
