c, removing the adenine base from Atp
Answer:
b
Explanation:
In the early 1600s, Galileo Galilei performed a series of experiments to measure the acceleration of a ball rolling down a smooth inclined plane. He tried several ways to measure time, including water clocks and his own pulse. Suppose his pulse rate was 66 beats per minute, and he counted 11 beats for the ball to roll down the plane. How many seconds was the ball rolling?

Sample Response: Surface tension is the result of
water molecules pulling inward with a strong attractive
force. This attractive force brings the molecules on the
surface of the water close together and causes the surface
of the water to be drawn toward the water molecules
beneath the surface. Since there are no water molecules
above the surface, there are uneven forces. This causes
surface tension, allowing the coin to float on the water's
surface

All the statement are correct about surface tension of water. Due to this force, water surface exhibit peculiar properties compared to the bulk of the system.
What is surface tension ?Surface tension is the potential for liquid surfaces that are at rest to condense into the smallest surface area. Razor blades and insects, which have a density greater than that of water, may float on the surface of the water without even getting partially buried because to surface tension.
Surface tension at liquid-air contacts originates from the liquid molecules' stronger attraction to one another owing to cohesion than to the air molecules due to adhesion.

How long does it take an airplane to fly 1200 miles if it maintains a speed of 300 miles per hour
Answer:
The answer is
4 hrsExplanation:
To find the time taken we use the formula
[tex]t = \frac{d}{v} \\ [/tex]
where
d is the distance covered
v is the velocity
t is the time
From the question
d = 1200 miles
v = 300 mi/hr
We have
[tex]t = \frac{1200}{300} = \frac{12}{3} \\ [/tex]
We have the final answer as
4 hrsHope this helps you

What are two ways engineers use their understanding of kinetic energy and potential energy to make their designs better/ safer?
Answer:
On a roller coaster, energy changes from potential to kinetic energy and back again many times over the course of a ride. Kinetic energy is energy that an object has as a result of its motion. Traditionally, the coaster cars are pulled up the first hill by a chain; as the cars climb, they gain potential energy.
Mechanical engineers are concerned about the mechanics of energy — how it is generated, stored, and moved. For example, mechanical and civil engineers ensure that there is sufficient potential energy, which is converted to kinetic energy, to move cars along an entire roller coaster ride.
What is kinetic energy ?"Kinetic energy is a form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy."
What is potential energy ?"Potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors."
Potential energy, stored energy that depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched. A steel ball has more potential energy raised above the ground than it has after falling to Earth.

Explanation:
A football was kicked so that it traveled 65 yards in 3.0 total seconds. What was the speed
and angle above horizontal that the ball was kicked?
Answer:
vx = 65 yd/3 sec = 21.7 yd/sec since horizontal speed is constant
vy = g t = (32 / 3) yd/sec^2 * 1.5 sec = 16 yd/sec where 32/3 is the acceleration due to gravity in yds / sec^2 and 1.5 is the time to travel each way in the vertical direction
V = (vx^2 + vy^2)^1/2 = (21.7^2 + 16^2)^1/2 = 27 yd/sec
tan theta = vy/vx = 16 / 21.7 = .737 theta = 36.4 deg
You can check using the range formula:
R = v^2 sin (2 theta) / g = 27^2 * .955 / (32 / 3) = 65.3 yds
The difference from 65 yds may be rounding error.

During a race, a sprinter increases from 4.0 m/s to 6.0 m/s over a period of 1.5 s. What is the sprinter’s average acceleration during this period? (10 Points) 1 meter per second squared 1.3 meters per second 2.0 meters per second 1.3 meters per second squared
Answer:
[tex]a=1.3\ m/s^2[/tex]
Explanation:
It is given that,
Initial velocity, u = 4 m/s
Final velocity, v = 6 m/s
Time, t = 1.5 s
We need to find the average acceleration of a sprinter during this period. We know that the rate of change of velocity of an object is equal to its acceleration. So,
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{(6-4)\ m/s}{1.5\ s}\\\\a=1.33\ m/s^2[/tex]
So, the acceleration of the sprinter is [tex]1.33\ m/s^2[/tex]. Hence, the correct option is (d).

What is the force of a lead ball that starts with a momentum of 7 kg*m/s and end with a momentum of 22 kg*m/s over a time of 31 seconds?
Explain how you got your answer.
Answer:
F = 0.483 N
Explanation:
Initial momentum, [tex]P_i= 7\ kg-m/s[/tex]
Final momentum, [tex]P_f= 22\ kg-m/s[/tex]
Time, t = 31 s
We need to find the force of a lead ball. We can use here the impulse momentum theorem.
[tex]\text{Change in momentum}=F\times t[/tex]
F is force
[tex]P_f-P_i=Ft\\\\F=\dfrac{P_f-P_i}{t}\\\\F=\dfrac{22-7}{31}\\\\F=0.483\ N[/tex]
So, the force is 0.483 N.
