Explanation:
explain how to identify the points under compression and tension
Answer:
Pls make me brainliest
Explanation:
the compression force is the force generated from compressing an object or substance. When shearing forces are aligned into each other, they are called compression forces.
The compression force is used to power everything from compression brakes to hand tools. The compressive strength of materials and structures is an important engineering consideration.
The compression force can be visualized by placing an object on a spring. When the spring is compressed and then released, the object is ejected into the air.
This is a result of the compression force that is generated from compressing the spring.
This system has a constant velocity, and there is an equilibrium because the tension in the cable, which is pulling up the object, is equal to the weight force, i.e., mg. Where M is a mass, and g is the acceleration caused by gravity, which is pulling down the object.
The Formula of Tension.
T = Mg
Tension word becomes from a Latin word meaning “to stretch.” Testing part of the force, Like one type of pull force. All physical objects that are in contact may exert forces on each other.
This contact forces different names based on these types of objects in contact. Where one of the objects exerting the force happens to be a rope, string, chain, or cable we call the force tensions

. A marble sphere with a diameter of 1/4 inch is fully immersed in the oil of density 0.961 g/cm3 . Calculate the buoyant force exerted on the marble sphere by the oil.
Answer:
See below ( was it REALLY 1/4 INCH??)
Explanation:
Calculate the volume of the sphere
v = 4/3 pi r^3
this times the density of the oil will give g displacement
then f = ma
4/3 pi (.25 in * 2.54 cm/inch) ^3 * .961 = 1.0307 gm
1.0307 gm is .0010307 kg
f = ma = .0010307 * 9.8 = .0101 N

Angie, brad, and carlos are discussing a physics problem in which two identical bullets are fired with equal speeds at equal-mass wood and steel blocks resting on a frictionless table. One bullet bounces off the steel block while the second becomes embedded in the wood block. All the masses and speeds are the same, says angie, so i think the blocks will have equal speeds after the collisions. But what about momentum? asks brad. The bullet hitting the wood block transfers all its momentum and energy to the block, so the wood block should end up going faster than the steel block. I think the bounce is an important factor, replies carlos. The steel block will be faster because the bullet bounces off it and goes back the other direction.
Answer:
Momentum must be conserved in the collision.
The steel block must move faster after the collision to preserve momentum.
If the steel block is moving faster it will aso have more kinetic energy.
(Note; If the bullet hits the steel block it will have some momentum in the reverse direction and thus have a greater change in total momtntum than the bullet that becomes imbedded in the wood block)

Displacement covered by the man calculated by using Pythagoras theorem is 10 km.
What is Pythagoras Theorem ?Pythagoras theorem states that, for a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the altitude and base sides.
Here,
The Pythagoras Theorem can be written as,
c² = b² + a²
where c is the hypotenuse, b is the base and a is the altitude of the triangle.
An example of application of the Pythagoras theorem is,
A man started walking from his home and covered a distance of 8 km towards the east and then turned right and walked a distance of 6 km towards the south, what is his displacement now from his starting point ?
A line drawn from his current position and his initial point represents the displacement covered by the man.
Let the starting point be A, then he walks to the point B and then he turns right and walks upto the point C.
Drawing a figure including all the data, we get a right angled triangle, ABC. So,
The base of the triangle, BC = 6 km
Altitude of the triangle, AB = 8 km
The displacement of the man = hypotenuse of the triangle
d = AC
According to Pythagoras Theorem,
AC² = BC² + AB²
AC² = 6² + 8² = 100
AC = √100
Therefore, displacement, d = AC = 10 km.
Hence,
Displacement covered by the man calculated by using Pythagoras theorem is 10 km.
