Some acquired mutations can be caused by things that we are exposed to in our environment, including cigarette smoke, radiation, hormones, and diet

An average amount acquired mutations are react able and caused by the things that’s are exposed to nature and the environment, such as radiation,hormones, and cigarette smoke.

Explain why a ping pong ball and bouncy ball of the same size have different weights

user100 [1]

Answer:

the material

Explanation:

weight is defined as the amount of force on the object because of gravity. ping pong balls and bouncy balls are made out of different materials that are different weights. most bouncy balls are also not hollow, unlike ping pong balls. these factors affect the weight of these objects.

What is the electric potential energy of a charge that experiences a force of 3.6x10^-4 N when it is 9.8x10^-5 m from the source

jekas [21]

Answer:

3.5 x 10^-8 J

Explanation:

We are given,

force experienced by a charge = 3.6 x 10^-4 N; and

distance of charge from the source of electric field = 9.8 x 10^-5 m

We know that, Energy = force x distance

therefore, to find the potential energy of the charge, we need to multiply its applied force with the given distance to get:

Electric potential energy of a charge = (3.6 x 10^-4) × (9.8 x 10^-5) = 3.5 x 10^-8 J

Therefore, the potential energy of a charge is 3.5 x 10^-8 J.

You throw a ball upward with an initial speed of 4.3 m/s. When it returns to your hand 0.88 s later, it has the same speed in th

djverab [1.8K]

Answer:

The acceleration is -9.8 m/s²

Explanation:

Hi there!!

When you throw a ball upward, there is a downward acceleration that makes the ball return to your hand. This acceleration is produced by gravity.

The average acceleration is calculated as the variation of the speed over time. In this case, we know the time and the initial and final speed. Then:

acceleration = final speed - initial speed/ elapsed time

acceleration = -4.3 m/s - 4.3 m/s / 0.88 s

acceleration = -9.8 m/s²

The distance covered by a car at a time, t is given by x = 20t + 6t4, calculate

Anni [7]

Answer:

(i) v = 44 m/s

(ii) a = 72 m/s^2

Explanation:

You have the following equation for the potion of a car:

$x=20t+6t^4$

(i) The instantaneous velocity is the derivative of x in time:

$\frac{dx}{dt}=20+(6)(4)t^3=20+24t^3$

for t = 1 is:

$v(t=1)=\frac{dx}{dt}=20+24(1)^3=44m/s$

(ii) The instantaneous acceleration is the derivative of the velocity:

$\frac{dv}{dt}=24(3)t^2=72t^2$

for t = 1

$a(t=1)=\frac{dv}{dt}=72(1)^2=72m/s^2$
