Use round wheels to roll the heap, help the weight by evacuating appended or contained protests, or place a smoother surface betwen the question and the floor. Water or different liquids can be utilized to diminish the protection, yet just on the off chance that they stay between the question and the floor.

A student claims that gravitational fields exist between objects that are not in contact with each other. She creates a diagram
VashaNatasha [74]

Answer:

Option B. The distance between the objects in Figure A is shorter than the distance between the objects in Figure B.

Explanation:

The force of attraction between two masses is given by the following equation:

F = GM₁M₂ / r²

Where:

F => is the force of attraction

M₁ and M₂ => are the masses of the two objects

G => is the gravitational constant.

r => is the distance between the two objects

From the above formula,

The force of attraction (F) is directly proportional to the product of the two masses and inversely proportional to the square of their apart.

This implies that:

1. An increase in the masses of the object will bring about an increase in the force of attraction and a decrease in the masses will leads to a decrease in the force of attraction.

2. An increase in the distance between the two masses will leads to a decrease in the force of attraction and a decrease in the distance between the two masses will lead to an increase in the force of attraction.

Considering the options given in the question above, option B gives the correct answer to the question.

The age of a piece of wood from an archeological site is to be determined using the Carbon-14 method. The activity of the sample
Bezzdna [24]

Answer:

4589.05 year

Explanation:

The relation of activity is given by A=A_0e^{\lambda t} we have given \frac{A}{A_0}=0.574

Half life T=5730\ years

We know that half life T=\frac{0.693}{\lambda }

\lambda =\frac{0.693}{5730}=1.2094\times 10^{-4}\ per\ year

So 0.574=e^{-1.2094\times 10^{-4}t}

e^{1.2094\times 10^{-4}t}=\frac{1}{0.574}=1.742

{1.2094\times 10^{-4}t}=ln1.742=0.555

t=\frac{0.555}{1.2094\times 10_{-4}}=4589.05\ year
