Explanation:
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?
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 metersTo 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.

Make me as brain liest plz
Pleaseee helpppp meeeeeee I will give pountsss
Answer:
8.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
285 = 75 × g
g = 285/ 75

2. A truck took 4 hours to complete a journey. At the first 2h,
it travelled at an average speed of 70 km/h. For the rest of
the journey, it travelled at an average speed of 80 km/h.
What was the total distance of the journey?
Answer:
300km
Explanation:
we use the formula s=d/t and solve for d.
d=st
s1=70km/h
s2=80km/h
t=2h
total d= (ts1)+(ts2)
=2(70)+2(80)
=300km
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
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

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

PLS HELP FOR MY GCSE REVISION! ill give brainliest
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

If 21.35 divides 12.96.
What’s the answer
Plzzz help me
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.
write down the relation between energy and power.
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.
