The gravitational force between Royce and Earth would double by the age of 16. Newton’s law of universal gravitation states that the gravitational force is proportional to the masses involved and inversely proportional to the square of the distance between them. At age 10, Royce weighed 30 kg, and by age 16, he weighed 60 kg. Since his mass doubled from 10 to 16 years, this results in a corresponding doubling of the gravitational force.
Response:
(A) 4* 6 ^ ⁻6 T m² (B) 2 * 10 ^ ⁻6 v
Clarification:
Solution
Given that:
A refrigerator magnet with a depth of approximately 2 mm
The estimated magnetic field strength of the magnet is = 5 m T
The Area = 8 cm²
Now,
(A) The magnetic flux ΦB = BA
Therefore,
ΦB = (5 * 10^⁻ 3) ( 4 * 10 ^⁻2) * ( 2 * 10^ ⁻2) Tm²
Thus,
ΦB = 4* 6 ^ ⁻6 T m²
(B) By employing Faraday's Law, the subsequent equation applies:
Ε = Bℓυ
Where,
ℓ = 2 cm equals 2 * 10 ^⁻2 m
B = 5 m T = 5 * 10 ^ ⁻3 T
υ = 2 cm/s = 2 * 10 ^ ⁻2 m/s
Therefore,
Ε = (5 * 10 ^ ⁻3 T) * (2 * 10 ^ ⁻2) (2 * 10 ^ ⁻2) v
E =2 * 10 ^ ⁻6 v
Answer:
The typical weight of a human heart is approximately 0.93 lbs.
Explanation:
Based on this,
the heart's weight constitutes about 0.5% of total body mass.
Total human weight = 185 lbs
Let the entire body weight be represented as w and the heart's weight as 
.
We aim to determine the heart's weight for a human
Using the provided information
Where, h = heart weight
w = human weight
The final weight of a human heart is 0.93 lbs.
Respuesta:
La magnitud de la aceleración resultante es 2.2 
Explicación:
La masa (m) del velero es 2000 kg
La fuerza que actúa sobre el velero debido a la marea del océano es 
= 3000N
Hacia el este significa que se da a lo largo de la dirección positiva del eje x
Entonces
= 3000N y 
= 0
La fuerza del viento que actúa sobre el velero es
6000N dirigida hacia el noroeste, lo que significa a un ángulo de 45 grados sobre el eje negativo x
Luego
= -(6000N) cos 45 grados = -4242.6 N
= (6000N) cos 45 grados = 4242.6 N
Por lo tanto, la fuerza neta que actúa sobre el velero en la dirección x es
= - 3000 N + 4242.6 N
= - 3000 N +4242.6 N
= 1242.6N
La fuerza neta que actúa sobre el velero en la dirección y es
= 0+ 4242.6N
= 4242.6N
La magnitud de la fuerza resultante =
Usando el teorema de Pitágoras de 1243 N y 4243 N
4420.8 N
F = ma

Answer:
0.018 J
Explanation:
The work required to bring the charge from infinity to the point P is equal to the change in its electric potential energy. This can be expressed as
where
represents the charge's magnitude
and 
signifies the potential difference between point P and infinity.
After substituting into the formula, we arrive at
