Answer:

\boxed {\boxed {\sf 157.5 \ Joules }}

Explanation:

Work is equal to the product of force and distance.

W=F*d

The box is being pushed with an effort (force) of 45 Newtons and the distance is 3.5 meters.

F= 45 \ N \\d= 3.5 \ m

Substitute the values into the formula.

W= 45 \ N * 3.5 \ m

Multiply.

W= 157.5 \ N*m

  • 1 Newton meter is equal to 1 Joule
  • Our answer of 157.5 N*m equals 157.5 J

W= 157.5 \ J

<u>157.5 Joules </u> of work are done on the crate.

For every subunit supplementary to a macromolecule in which one water molecule is detached. Macromolecule polymers are broken down by breaking bonds among subunits. This procedure is named hydrolysis and is the opposite of dehydration. During hydrolysis the hydrogen atom is supplementary to one monomer and a hydroxyl cluster to the other and by breaking the covalent bond in the middle of the monomers.

The center of the Hubble space telescope is 6940 km from Earth’s center. If the gravitational force between Earth and the telesc
Law Incorporation [45]
The gravitational force between two objects is given by:
F=G \frac{m_1 m_2}{r^2}
where
G is the gravitational constant
m1 and m2 are the masses of the two objects
r is the separation between the two objects

The distance of the telescope from the Earth's center is r=6940 km=6.94 \cdot 10^6 m, the gravitational force is F=9.21 \cdot 10^4 N and the mass of the Earth is m_1=5.98 \cdot 10^{24} kg, therefore we can rearrange the previous equation to find m2, the mass of the telescope:
m_2 =  \frac{Fr^2}{Gm_1}= \frac{(9.21 \cdot 10^4 N)(6.94\cdot 10^6)^2}{(6.67\cdot 10^{-11})(5.98\cdot 10^{24})} =11121 kg
