When an object is immersed in a fluid (in this case water, but may include both liquids and gases) the fluid exerts an upward force on the object which is called buoyancy force or up-thrust. Archimedes’ Principle states that the buoyant force (upward push or force) applied to an object is equal to the weight of the fluid that the object takes the space of by that object. Thus when an object is placed in water the rise in the water level is dictated by the mass of that object.
So for example if you fill a bucket with water and you drop a stone in that bucket, if you measure the weight of the water that overflows from the bucket due to the stone being dropped into the bucket is equivalent to the pushing force that the water has on the stone (as the stone drops to the bottom of the bucket the water is pushing it to stay afloat but the rock is more dense than water and as such its downthrust exceeds water's upthrust).
b. red giants
c. white dwarfs
d. main sequence stars
Answer:
a and d are correct
Explanation:
a. neutron stars
d. main sequence stars
Are smaller than the sun but I'm not sure about white dwarfs because a typical white dwarf is about as massive as the Sun, yet only slightly bigger than the Earth.
Answer:
1.1 x 10⁵m/s²
Explanation:
Given parameters:
Velocity = 452m/s
distance = 0.93m
Unknown:
Acceleration of the bullet = ?
Solution:
To solve this problem, we use one of the kinematics equation which is given below:
V² = U² + 2aS
V is the final velocity
U is the initial velocity = 0m/s
a is the unknown acceleration
S is the distance traveled
So;
452² = 0² + (2 x a x 0.93)
204304 = 1.86a
a = 1.1 x 10⁵m/s²
The acceleration of the bullet in the gun barrel can be calculated using the kinematic equation for motion. By substituying the given values into the equation, we find the acceleration to be approximately 1.095 x 10^5 m/s^2.
The subject of this question is Physics, specifically a topic under mechanics known as kinematics. The problem given can be solved using kinematic equations which are used to describe the motion of an object without considering the forces that cause it to move. In this case, the final velocity (vf) of the bullet is given as 452 m/s, the initial velocity (vi) is assumed to be 0 as it starts from rest, and the distance (d) is given as 0.93 m. We are asked to determine the value of acceleration (a).
Using the kinematic equation vf2 = vi2 + 2ad and substituting the given values, we get (452 m/s)2 = 0 + 2*a*0.93 m. We can rearrange to solve for acceleration to get: a = (452 m/s)2 / (2*0.93 m) = 109523.66 m/s2.
So, the acceleration of the bullet in the gun barrel is approximately 1.095 x 105 m/s2.

if the same forces are applied, then the door will not move due to similar strength. So, regardless the door won't move.
Force is a parameter which can be defined as either pushing or pulling of the object resulting in the object’s interaction or movement, without force the objects can not move, be stopped or change the direction.
Force is a quantitative interacting parameter between two physical bodies, means an object and its environment, there are different types of forces in nature.
If an object is in its moving state then it will be either static or motion, the position of the object will only be changed if it is externally pushed or pulled.
The contact type of force are the force that occurs when we apply some effort on an object such as Spring Force, Applied Force, Air Resistance Force, Normal Force, Tension Force, Frictional Force
Non-Contact type of forces are another type of forces occur from a distance such as Electromagnetic Force, Gravitational Force, Nuclear Force

Explanation:
i was always interested in certain biomechanics, how things lived and what worked for them to stay alive, but more specifically how organisms grow. i can also apply to this to industrial engineering. The parts in a machine for it do its job, and how they have to be not just accurate, but precise every time; The amount of calculation and careful precison for it to be effective. i would love to understand in general why things work the way they do.
