Answer:
if it is a gene mutation then it is during the S phase, and if it is a chromosome mutation, then during metaphase or anaphase.
Explanation: I think it happens in the interphase
When a mutation occurs in mitosis, stage of Mitosis is interphase.
What is mutation?Mutation that occurs in mitosis typically causes tumor.
Genetic mutations occur during the S phase of the cell cycle i.e during interphase before mitosis begins. When DNA is replicated, error would cause a mutation in the genetic code. Chromosomal nondisjunction denotes the failure of replicated chromosomes to separate causing extra or missing chromosomes in the daughter cells to occur. This mutation can occur during mitosis.
Thus, When a mutation occurs in mitosis, stage of Mitosis is interphase.

Answers
Answer:
50 s
Explanation:
Given:
Δx = 0.005 m
v₀ = 0 m/s
t = 0.50 s
Find: a
Δx = v₀ t + ½ at²
0.005 m = (0 m/s) (0.50 s) + ½ a (0.50 s)²
a = 0.04 m/s²
Given:
Δx = 50 m
v₀ = 0 m/s
a = 0.04 m/s²
Find: t
Δx = v₀ t + ½ at²
50 m = (0 m/s) t + ½ (0.04 m/s²) t²
t = 50 s

Two beaker of water A and B , initially are at the same temperature.The temperature of the
water in beaker A is increased by 10F and the temperature of water in beaker B is increased
10 K. After these temperature change,which beaker of water has the higher temperature?
Answers
Answer :
beaker A , it is because the temperature increases is higher than beaker B.
Formula
(10°F − 32) × 5/9 + 273.15 = 260.928K
10 degrees fahrenheit = 260.928 kelvins
Formula
(10K − 273.15) × 9/5 + 32 = -441.7°F
10 kelvins = -441.67 degrees fahrenheit
beaker A , 10°F = -12.222 °C
beaker B , 10k = -263.15 °C
Beaker A of water will have a higher temperature than the temperature of beaker B.
How to change the temperature from Fahrenheit to Celcius?To convert the temperature Fahrenheit to Celsius formula is used from the scale Fahrenheit to Celsius. Both scales provide a way to measure the object’s hotness and coldness and are used to measure the temperature. The symbol used to express Fahrenheit is °F while the symbol used for Celsius is °C.
The formula used to change the temperature from Fahrenheit to Celsius as follows:
°C = (°F- 32)5/9
The temperature of beaker A is increased by 10°F. So the change in temperature in the Celcius scale is :
T(°C) = (10- 32)5/9
T(°C) = -12.22°C
The temperature of beaker B is increased by 10 K, then the temperature in Celcius is:
T(°C) = 10 - 273.15
T(°C) = - 263.15°C
Therefore, the temperature of beaker A will be higher after these changes if initially, both are at the same temperature.

A car is initially moving at 10.5 m/s and accelerates uniformly to reach a speed of 21.7 m/s in 4.34 s. How far did the car move during this acceleration?
A. 69.9m
B. 6.99m
C. 69.6m/s
D. 6.99m/s
Answers
Answer:
A. 69.9m
Explanation:
Given parameters:
Initial velocity = 10.5m/s
Final velocity = 21.7m/s
Time = 4.34s
Unknown:
Distance traveled = ?
Solution:
Let us first find the acceleration of the car;
Acceleration = [tex]\frac{v - u}{t}[/tex]
v is final velocity
u is initial velocity
t is the time
Acceleration = [tex]\frac{21.7 - 10.5}{4.34}[/tex] = 2.58m/s²
Distance traveled;
V² = U² + 2aS
21.7² = 10.5² + 2 x 2.58 x S
360.64 = 2 x 2.58 x S
S = 69.9m

A car is traveling down the highway cruise control at 50m/s (this means its is traveling with a constant velocity NOT accelerating). If it does this for 5 minutes (300s), how far does it travel?
Answers
Given parameters:
Speed of car = 50m/s
Time of travel = 5minutes (300s)
Unknown;
Distance of travel = ?
To solve this problem, we need to understand how speed relates with distance and time.
Speed is a physical quantity. It is the distance traveled divided by time taken.
Speed = [tex]\frac{distance}{time}[/tex]
So,
Distance = speed x time
Input the parameters and solve for the distance;
Distance = 50m/s x 300s
Distance = 15000m
The distance covered during this time interval and speed is 15000m

Explain Kinetic and potential energy
Answers
Answer:
Energy implies as the object’s capability to perform work. It is something that cannot be created or destroyed but can only be transformed. An object loses its energy, when it performs work, whereas it gains energy when the work is performed on it. Energy is broadly classified as kinetic energy and potential energy. While kinetic energy is the energy which an object contains because of a particular motion.
On the other hand, potential energy is the stored energy, because of its state of rest. As both the two forms of energy are measured in joules, people get easily confused between these two. So, take a read of the article which will help you to understand the differences between kinetic and potential energy.

A truck traveling at a velocity of 33m/s comes to a halt by decelerating at 11m/s^2. How far does the truck travel in the process of stopping. identify known variables such as V, V0, a, t, and delta x.
Answers
Answer:
The truck was moving 16.5 m/s during the time it took to stop, which was 3 seconds.
Initial velocity = 33 m/sFinal velocity = 0 m/sAverage velocity = (33 + 0) / 2 m/s = 16.5 m/sExplanation:
First, how long does it take the truck to come to a complete stop?( 33 m/s ) / ( 11 m / s^2 ) = 3 secondsThen we can look at the average velocity between when the truck started decelerating and when it came to a complete stop. Because the deceleration is constant (always 11m/s^2) we can use this trick.The time taken to stop the truck is 3 seconds. The final velocity is zero. Then, the distance travelled by the truck is 49.5 m.
What is acceleration ?Acceleration is a physical quantity that, measures the rate of change in velocity. It is a vector quantity thus having both magnitude and direction. It can be defines as the ratio of change in velocity to the change in time.
Given initial velocity = 13.5 m/s
final velocity is zero since the bicycle is stopping.
then Δt = Δv/a
Δt = 33 m/s/ 11 m/s² = 3 seconds.
Hence, the truck will take 3 s to complete stop.
The distance covered within this time can be determined using the equation as follows:
s = u t + 1/2 at²
where u is the initial velocity
The acceleration a = - 11 m/s² the minus sign is due to deceleration.
s = (33m/s × 3 s) + (-11 m/s² ×3 s ×3 s) = 49.5 m.
Therefore, the truck will travel up to 49.5 m before stopping.

a) Determine the force that the 2kg block exerts on the 4kg block
b) Determine the force that the 4kg block exerts on the 2kg block.
Answers
Answer:
a) -4 N
b) +4 N
Explanation:
Draw a free body diagram for each block.
For the large block, there are 2 forces: 12 N pushing to the right, and F pushing to the left.
For the small block, there is 1 force, F pushing to the right.
There are also weight and normal forces in the vertical direction, but we can ignore those.
Sum of forces on the large block in the x direction:
∑F = ma
12 − F = 4a
Sum of forces on the small block in the x direction:
∑F = ma
F = 2a
2F = 4a
Substitute:
12 − F = 2F
12 = 3F
F = 4
The small block pushes on the large block 4 N to the left (-4 N).
The large block pushes on the small block 4 N to the right (+4 N).

Answers
Answer:
(a). The speed at the moment of being thrown is 30.41 m/s.
(b). The maximum height is 47.18 m.
Explanation:
Given that,
Weight of stone = 3.00 N
Height = 15 m
Speed = 25.0 m/s
(a). We need to calculate the speed at the moment of being thrown
Using work energy theorem
[tex]W=\dfrac{1}{2}m(v_{2}^2-v_{1}^2)[/tex]
[tex]-mg\times d=\dfrac{1}{2}m(v_{2}^2-v_{1}^2)[/tex]
Put the value into the formula
[tex]-9.8\times15=\dfrac{1}{2}\times(v_{2}^2-v_{1}^2)[/tex]
[tex]-2\times9.8\times15=25^2-v_{1}^2[/tex]
[tex]-v_{1}^2=-300-25^2[/tex]
[tex]v_{1}=\sqrt{925}[/tex]
[tex]v_{1}=30.41\ m/s[/tex]
(b). We need to calculate the maximum height
Using work energy theorem
[tex][tex]W=\dfrac{1}{2}mv_{2}^2-\dfrac{1}{2}mv_{1}^2[/tex]
[tex]mg\times d=\dfrac{1}{2}mv_{2}^2-\dfrac{1}{2}mv_{1}^2[/tex]
Here, [tex]\dfrac{1}{2}mv_{2}^2[/tex]=0
[tex]-(mg)\times d=\dfrac{1}{2}mv_{1}^2[/tex]
[tex]d=\dfrac{v_{1}^2}{2g}[/tex]
Put the value into the formula
[tex]d=\dfrac{30.41^2}{2\times9.8}[/tex]
[tex]d=47.18\ m[/tex]
Hence, (a). The speed at the moment of being thrown is 30.41 m/s.
(b). The maximum height is 47.18 m.
