In your own words, explain why the dishes remain in place when the magician pulls the cloth out from under them.
Newton's first law states that unless acted with by an external force, the dinnerware will remain immobile. The horizontal force acting on the objects on the table in this example is the frictional force between them and the table cloth, which sets them in motion.
According to Newton's second law, the force required to accelerate the tableware is proportional to the rate of acceleration. When the tablecloth is slowly pushed, the dinnerware adjusts to fit the modest rate of acceleration and moves with it. When the tableware is pulled swiftly, it needs to accelerate at a faster pace to keep up; but, the effort required to do so is larger than the frictional force available, thus it lags behind. The tableware 'stays put' when the cloth is tugged quickly.''
This question covers one of the most enigmatic aspects of our universe! Inertia is the easy answer to your question. In other words, because of inertia, when you remove the table linen off a table full of dishes, the dishes stay put. Matter's inertia is a property that characterizes its resistance to change in motion. When you're jogging and try to turn, you'll find that the faster you go or the bigger you are, the more difficult it is to shift direction.
Other examples of inertia include the following. Another example of inertia is when you are riding in a car and the driver rounds a corner and you feel pushed toward the door or over to the driver.
The dishes' inertia comes into play when the magician removes the cloth from underneath them.
The propensity of objects to resist changes in their state of motion is known as inertia. The dishes seek to preserve their original condition of rest when the fabric is quickly pulled because of inertia.
The dishes' and the cloth's friction is insufficient to rapidly overcome this inertia. As a result, the dishes initially hold in place before friction gradually takes over and causes them to slide.
Thus, the careful balance between inertia and friction results in this seemingly supernatural effect, producing a visually stunning illusion.

In physical weathering, how are ice and plant roots similar?
Both break open rocks by expanding in a crack.
Both cause abrasion and slowly break down rocks.
Both require many cycles of freezing and melting.
Both result from dramatic changes in temperature.
Answer:
A break open rocks from in cracks
Explanation:
Ice freezes in the crack and expands. Plants start growing in the crack and grow out of it. Both of these cause the rock to slowly break in half from the crack.

ill give brainliest What will the acceleration of a falling 8 kg object be if it has 7 Newtons of air resistance?
Answer:
Given:
M= 8kg
F= 7N
Unknown:
Acceleration of a falling object
Formula:
a = F/m
Solution and Final Answer:
a = 7 kg.m/s² ÷ 8 kg
a = 0.88 m/s²
because the divisor and dividend there are the same units so cancel it(kg) then the rest is m/s² so it will be the unit of 0.88 will become 0.88 m/s²

Answer:
B.
Explanation:
Since the gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

The greater the __ and __ the more kinetic energy there will be. (Fill in the blanks)
Answer the gerater mass and the faster the object moves the more kenetic enegry there would be
Explanation:
Answer:
The greater the mass and acceleration the more kinetic energy there will be.
Kinetic energy and Explanation
The kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.
Mass and Explanation
Mass is both a property of a physical body and a measure of its resistance to acceleration when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. The basic SI unit of mass is the kilogram.
Acceleration and Explanation
Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.
Where are the magnetic field lines closest together, and what does that tell you about the strength of the magnetic field?

Answer:
39,200J
Explanation:
just took the test
The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J
What is potential energy ?Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.
mass(m) = 10kg
g (acceleration due to gravity) = 9.8m/s^2
altitude(height (h)) = 400m
Meteor's Potential energy = m * g * h
= 10 * 9.8 * 400 = 39200 J
correct option will be a) 39200 J
