Answer:

0.05 m

Explanation:

From the question given above, the following data were obtained:

Mass of first object (M1) = 9900 kg

Gravitational force (F) = 12 N

Mass of second object (M2) = 52000 kg

Distance apart (r) =?

Gravitational constant (G) = 6.67×10¯¹¹ Nm²/Kg²

Thus, we can obtain the distance between the two objects as shown below:

F = GM1M2/r²

12 = 6.67×10¯¹¹ × 9900 × 52000 /r²

Cross multiply

12 × r² = 6.67×10¯¹¹ × 9900 × 52000

Divide both side by 12

r² = (6.67×10¯¹¹ × 9900 × 52000)/12

Take the square root of both side

r = √[(6.67×10¯¹¹ × 9900 × 52000)/12]

r = 0.05 m

Therefore, the distance between the two objects is 0.05 m

3. Nuclear energy is a controversial eneray resource. Find out why.

a_sh-v [17]

Explanation:

Cons

Nuclear energy is very unsafe compared to other energy sources. A leakage or explosion can release dangerous radioactive elements from the plant causing lethal mutations on the organisms in the ecosystems.
Nuclear energy use produces nuclear waste that needs to be stored safely to avoid contaminating the environment. Finding a safe place to store the waste and how to contain the waste over 1000s of years is very costly and challenging.

Pros

Nuclear energy is very clean energy because it releases no greenhouse emissions into the atmosphere that may cause global warming.
Its is a cheap form of energy because it releases a lot of energy relative to the investment.

A Carnot heat engine has an efficiency of 0.400. If it operates between a deep lake with a constant temperature of 298.0k and a

tatuchka [14]

Answer:

496.7 K

Explanation:

The efficiency of a Carnot engine is given by the equation:

$\eta = 1 - \frac{T_H}{T_L}$

where:

$T_H$ is the temperature of the hot reservoir

$T_C$ is the temperature of the cold reservoir

For the engine in the problem, we know that

$\eta = 0.400$ is the efficiency

$T_C = 298.0 K$ is the temperature of the cold reservoir

Solving for $T_H$ , we find:

$\frac{T_C}{T_H}=1-\eta\\T_H = \frac{T_C}{1-\eta} =\frac{298.0}{1-0.400}=496.7 K$

What is electric force

AysviL [449]

Electric force occurs between positive and negative electric charge. It can be calculated with formula $F=\frac{Q_1Q_2}{A\epsilon_0\epsilon_r}$ where F is force, Q1 and Q2 are charges, A is area of object usually ball ( $A=4\pi r^2$ ) because we describe charges as points in space like electrons and protons, $\epsilon_0$ is a natural dielectric constant of empty space or vacuum ( $\epsilon_0=8.85\times10^{-12}\mathsf{\frac{As}{Vm}}$ ) and $\epsilon_r$ also known as relative dielectric variable.

There are two types of the force:

1. Attractive electric force

2. Repulsive electric force

Attractive electric force occurs between positively and negatively charged objects while repulsive occurs between equally charged objects for eg. (positive and positive will repulse).

If a ball is thrown upward with an initial velocity of 30.0 m/s how much time does it take to reach its maximum height

Masteriza [31]

Gravity makes an upward-moving object move 9.8 m/s slower every second.

(30 m/s) / (9.8 m/s²) = 3.06 seconds (rounded)
