D. Exercise and attention to diet need to go together to build health.
It would be D because if you’re losing weight then you need to eat less calories than you burn in a day so then your body has to burn fat.

m= 0. 113 kg

W = 1.1074 N

g = 9.8 m/ s²

9.

m= 870 kg

W = 8526 N

g = 9.8 m/s²

10.

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

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

After 15.2 days only 3 g will be present

A force of 10 N works on a ball over a distance of 5 m. The force is perpendicular to the displacement of the ball. What is the total work done by the force?​

Answers

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:

Force = 10 NewtonDistance = 5 meters

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.

How do you determined the atomic mass and mass number of an atom?

Answers

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.

If 21.35 divides 12.96.
What’s the answer
Plzzz help me

Answers

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.


This car started from rest at a
position of 4 km from the reference
point. It accelerated at 2.2 m/s^2
for a period of 0.5 minutes. How far
from the reference point is the car
located after the acceleration ends?


2 km

5 km

1 km

6 km

Answers

Answer:4.99km

Explanation:

We'll use s for distance, and t for time in seconds.

s = (1/2)at²

t = 0.5 minute*(60sec/1min)=30 sec

s = (1/2)*(2.2m/s²)(30sec)²

s = 990m

Reference point is 4km at start.  Distance from reference point is 9km + 0.990km = 4.99km

the journey, it travelled at an average speed of 80 km/h.
What was the total distance of the journey?

Answers

Answer:

Explanation:

we use the formula s=d/t and solve for d.

s1=70km/h

s2=80km/h

t=2h

write down the relation between energy and power. ​

Answers

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.
