If the force squeezing two surfaces together is decreased, the force of dry sliding friction between the two surfaces will most likely decrease.
therefore your answer is B)decrease
Hope this helps you- have a good day bro cya)
The force of dry sliding friction between the two surfaces will most likely decreases.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

This graph shows how the potential energy of a reaction system changes
over time. Which statement is true for this system?
B
Potential energy
С
Reaction progress
O A. The potential energy of the reactants is greater than the potential
energy of the products
OB. The height of the curve at point A represents the activation energy
O C. The height of the curve at point B represents the activation energy.
O D. The potential energy of the products is greater than the potential
energy of the reactants.
The potential energy of the reactants is greater than the potential energy of the products.
What is potential energy of reaction?Potential energy of a reaction is the stored energy that helps in breaking the bond of a compound during a chemical reaction.
The bonds present in the reactants in the reaction mixture split in the presence of the activation energy to release energy and form the product.
Thus,, option A. The potential energy of the reactants is greater than the potential energy of the products.

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.

The half-life of Radon-222 is 3.8 days. Calculate how long a 48g sample of radon will last before it contains only 3g of radon.
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
4 half-lives * 3.8 days / half-life = 15.2 days
After 15.2 days only 3 g will be present
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.

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

See below:
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.

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
