Please help me with part 2. Will give brainliest

Answer:

m= 0. 113 kg

W = 1.1074 N

g = 9.8 m/ s²

m= 870 kg

W = 8526 N

g = 9.8 m/s²

a) weight on earth:

weight = mass × acceleration due to gravity (g)

g on earth = 9.8 m/s²

W = 75 × 9.8

W = 735 N

b) g on Mars

285 = 75 × g

g = 285/ 75

g = 3.8 m/ s²

Answer:

1.647376

Explanation:

Change the divisor 12.96 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.

We then have the equations:

2135 ÷ 1296 = 1.647376

and therefore:

21.35 ÷ 12.96 = 1.647376

Both calculated to 6 decimal places.

Answer:They repel each other

Step by Step Explanation :

If you bring a positive object near the electroscope, it will attract the electrons toward the terminal. The leaves will move away from each other. You can also use this process with a positive object to charge the electroscope.

Explanation:

Motion is what makes something move, there are different types and different ways to make motion, motion also comes with forces.

To figure out the motion type, we can simply see the wording of the sentence:

1) Air Resistance is the motion of air, it would be pushing up to stop the fall a bit.

2) We can neglect the resistance by being straight so we have to deal with less of it.

3) This motion is not in motion as nothing happened/happening.

4) This is friction as the friction of the ground and turning the car is slowing it down.

5) The motion is going in any direction as it depends on the start of the asteroid and its starting angle.

6) If its not moving; there is no motion.

7) We can neglect it by going on a 0 degree slope.

8) We simply have to do nothing as its already a law and will happen naturally.

9) The motion is basic motion with some friction due to its scenario.

Explanation:

magnitude=force/charge

=(2.6N)/(1.5 ×10^-6)

=1.7 × 10^6 N/C

Since the force is perpendicular to the displacement of the ball, the total work done by the force is 50 Nm.

Given the following data:

To find the total work done by the force:

The work done by an object is the product of the perpendicular force acting on the object and the distance it covers.

Mathematically, work done is given by the formula:

[tex]Work\;done = Force[/tex] × [tex]distance[/tex]

Substituting the given parameters into the formula, we have;

[tex]Work\;done = 10[/tex] × [tex]5[/tex]

Work done = 50 Nm.

Energy is what makes change happen and can be transferred form one object to another. Energy can also be transformed from one form to another. Power is the rate at which energy is transferred. It is not energy but is often confused with energy.

Energy and power are closely related but are not the same physical quantity. Energy is the ability to cause change; power is the rate energy is moved, or used.

Answer:

For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.

Answer:

48 / 3 = 16

1 / 16 of the original amount is to remain

4 half lives = 1/2 * 1/2 * 1/2 * 1/2 = 1/16

After 4 half lives 1/16 of the original amount is present

4 half-lives * 3.8 days / half-life = 15.2 days

After 15.2 days only 3 g will be present

Known as the “plica semilunaris,” it's much more prominent in birds and a few mammals, and functions like a windshield wiper to keep dust and debris out of their eyes. But in humans, it doesn't work. It's vestigial, meaning it no longer serves its original purpose.
