Answer:
2600 cubic centimeters
Explanation:
Volume of the edible fruit is equal to :
⇒ Volume (fruit) - Volume (seed)
⇒ 4/3π(3r)³ - 4/3πr³
⇒ 27 x 4/3πr³ - 4/3πr³
⇒ 100 (27 - 1)
⇒ 2600 cubic centimeters
The volume of the edible fruit, rounded to the nearest cubic centimeter, is approximately 1188 cubic centimeters.
Given that the volume of the seed is 100 cubic centimeters, we can use the formula for the volume of a sphere to relate the radius and volume:
V(seed) = (4/3)πr³
100 = (4/3)πr³
Next, we can determine the radius of the fruit by multiplying the radius of the seed by 3:
R(fruit) = 3r
V(fruit) = (4/3)π(R(fruit)³ - r³)
V(fruit) = (4/3)π((3r)³ - r³)
V(fruit) = (4/3)π(27r³ - r³)
V(fruit) = (4/3)π(26r)
Now, substitute the value of r from the first equation into the expression for V(fruit):
V(fruit) = (4/3)π(26 × ∛(100/(4/3)π))
V(fruit) = 1188 cubic centimeters
Therefore, the volume of the edible fruit, rounded to the nearest cubic centimeter, is approximately 1188 cubic centimeters.

A charge Q acts on a test charge to create an electric field, E. The strength of the field is measured at 8 N/C at 40 cm away. What would the field strength be 80 cm away with a charge of 1/2 Q? Explain.
The electric field strength created by a charge decreases with increasing distance from the charge. The relationship between the electric field strength (E) and the distance (r) from the charge is given by the inverse square law:
E ∝ 1/r^2
Let's consider the given scenario:
At a distance of 40 cm (0.4 m) from the charge, the electric field strength is measured as 8 N/C.
We want to determine the electric field strength at a distance of 80 cm (0.8 m) from the charge when the charge is reduced to 1/2 Q.
First, we can set up a proportionality based on the inverse square law:
(E1)/(E2) = (r2^2)/(r1^2)
Substituting the given values:
8/E2 = (0.8^2)/(0.4^2)
Simplifying the equation:
E2 = 8 * (0.4^2)/(0.8^2)
E2 = 8 * 0.16/0.64
E2 = 2 N/C
Therefore, at a distance of 80 cm from the charge, when the charge is reduced to 1/2 Q, the electric field strength would be 2 N/C.
The strength of an electric field depends on the magnitude of the charge creating the field and the distance from the charge. In this case, since the charge is reduced to 1/2 Q, the electric field strength is also halved.
Additionally, as we move twice as far away from the charge (from 40 cm to 80 cm), the electric field strength decreases according to the inverse square law. As a result, the electric field strength is reduced to 2 N/C at a distance of 80 cm.

What is the potential at a distance of 5. 0 ? 10-10 m from a nucleus of charge 50e?
The electric potential at a distance from a nucleus of charge 50e is 144 Volts.
What is electric potential?The potential is the work done by the test charge to move it from infinity to a particular point.
The potential is given by the relation
V = kQ / r
The distance of a point from the nucleus is 5.0 × 10⁻¹⁰ m and the charge on the nucleus is 50 e = 50 × 1.9 × 10⁻¹⁹ C.
k = 9 × 10⁹ kg-m²/s²-C²
Here, Q is the charge, r is the distance and k is the constant.

Do you think that push-ups (pushing your body weight up from the floor) or shoulder press (pushing weights above your head) will do a better job of helping you build muscles? Defend your answer using words and equations.
Answer:
Push-ups. Let M1 be the mass of the body and M2 be the mass of weights. Assume that M1 must be heavier than M2. Since M1 is heavier, M1 requires more force, and therefore work to be applied, let F1=M1*g. To bring our body back up, we need a force bigger or equal (if already in motion) to F1.
Let F2 = M2*g
Since F1 has to be bigger than F2 due to mass, we can build an equation for energy. Let X be a displacement, which is equal in both situations. Constructing a change of energy equation we can see that work done to lift the body is greater:
W1=F1*x
W2=F2*x
Where W1 is the work of the hands-on body, and W2 is the work of lifting weights. W1 has to be larger than W2. Since more work in W1, more muscle will be needed to complete a repetition, but only assuming that M1 > M2.
