Answer:
the thumb
Explanation:
pressure is exerted more by an area of small surface area.
pressure is got by P=Force/Area in contact
on the thumb there is a smaller area in contact. so as the area reduces, the force exertes becomes greater.

a system absorbs 35J of heat and in the process it does 11J of work if the initial internal energy is 205J a,what is the final internal energy b,the system follows a different thermodynamic path to the same final state and does 15J of work, what is the heat transferred ?
Answers
Answer:
[tex]a)uf = 205 + 35 - 11 \\ = 240 - 11 \\ = 229j \\ b)q(heat \: transferd) = 229 - 205 - 11 \\ = 24 - 11 \\ = 13j \\ thank \: you[/tex]
The heat transferred is
a) u f = 205+35-11
=240-11
= 229 j
b) q (heat transferred ) = 223-205-11
= 24-11
= 13 j
What is the difference between course and process in thermodynamics?
While a thermodynamic gadget passes thru an exchange in the state, a succession of states exceeded could be termed as a course of the device or direction of an alternate country. If the route of change of kingdom is completely distinctive, route of alternate of the nation may be termed as thermodynamic manner.
The technique is described via a direction, which is the non-stop collection of consecutive states via which the machine passes, consisting of the initial nation, the intermediate states, and the very last state. The process has a course along the course.
An asset whose price would not depend upon the course taken to attain that unique price is thought to as kingdom capabilities or point features. In contrast, those capabilities which do depend upon the direction from points are referred to as course features.

7. A train is traveling with an initial velocity of 20.1 m/sec. If the brakes can apply a maximum
acceleration of -0.0500 m/sec”, how long will it take the train to stop?
Answers
The time that takes for the train that is traveling with an initial velocity of 20.1 m/s to stop is 402 seconds.
The time that will take for the train to stop can be calculated with the following kinematic equation:
[tex] v_{f} = v_{i} + at [/tex] (1)
Where:
[tex] v_{f}[/tex]: is the final velocity = 0 (when it stops)
[tex] v_{i}[/tex]: is the intial velocity = 20.1 m/s
a: is the acceleration = -0.0500 m/s²
t: is the time =?
By solving equation (1) for t, we have:
[tex] t = \frac{v_{f} - v_{i}}{a} = \frac{0 - 20.1 m/s}{-0.0500 m/s^{2}} = 402 s [/tex]
Therefore, it will take 402 seconds for the train to stop.

Answer:
Q:
What characteristic is shared by sunspots, solar flares, and coronal mass ejections? Select the two correct responses.
A:
They tend to occur during active periods of the solar cycle. & They are caused by outward fluctuations of the sun's magnetic field.
Q:Drag each item to the correct location.
A: sunspot: cooler area on suns surface where the magnettic field emerges
solar flare: intense burst of radiation coming from the rapid release of magnetic energy
coronal mass ejection: large bubble of plasma from the rapid release of magnetic energy
Q: Which is the cause of the sun's magnetic properties?
A: uneven churning of plasma
Explanation:
took quick check
good luck yall
The uneven churning of plasma is the cause of the sun's magnetic properties, therefore the correct answer is option B.
What is a magnetic field?A magnetic field could be understood as an area around a magnet, magnetic material, or an electric charge in which magnetic force is exerted.
For a simple bar magnet, N-pole and S-pole are the points on a magnet that have the strongest magnetic field. The magnetic field originates from the north pole and terminates in the south pole of a magnet.
The positively charged ions and negatively charged electrons that make up the plasma of the Sun move around a lot due to its high temperatures. Multiple intricate magnetic fields that twist and turn are produced by the moving plasma. A magnetic field is produced by the extremely hot plasma that escapes from the Sun as the solar wind.
Thus, The sun's magnetic properties are caused by uneven plasma churning, so option B is the correct answer.

The ball is hurled upward into space, it climbs steadily until it collides with an obstruction in its path.
What is gravitational force?All mass-bearing objects are attracted by gravitational force. Because it consistently attempts to bring masses together rather than push them apart, the gravitational force is referred to as attractive.
As we know, the gravitational force is given by:
[tex]\rm F = \dfrac{Gm_1m_2}{r^2}[/tex]
Where G is the gravitational constant.
m1 and m2 are masses.
r is the distance between the masses.
As we know,
There is no gravity in space, the ball is not subject to the effects of gravity. When a ball is hurled upward into space.
It climbs steadily until it collides with an obstruction in its path.

BRAINLIEST : A car starts from rest and accelerates at a rate of 40 m/s2 over a time if 2.4 s. How fast is the car going at the end of this time interval?
Please explain
Answers
Answer:
[tex]\boxed {\boxed {\sf 96 \ m/s}}[/tex]
Explanation:
We are asked to find the final velocity of the car given the acceleration and time. We can use the following kinematics equation to calculate the final velocity.
[tex]v_f=v_i+(a \times t)[/tex]
The car starts from rest, so the initial velocity is 0 meters per second. It accelerates a rate of 40 meters per square second over a period of time of 2.4 seconds.
[tex]v_i[/tex]= 0 m/s a= 40 m/s²t= 2.4 sSubstitute the values into the formula.
[tex]v_f= 0 \ m/s + ( 40 \ m/s^2 \times2.4 \ s)[/tex]
Solve inside the parentheses.
40 m/s/s * 2.4 s = 40 m/s * 2.4=96 m/s[tex]v_f= 0 \ m/s + (96 \ m/s)[/tex]
Add.
[tex]v_f= 96 \ m/s[/tex]
The final velocity of the car is 96 meters per second.

Give a reasonable order-of-magnitude estimate of the number of golf balls that would fill a home
swimming pool
Answers
An order of magnitude is a number of the form 10^n such that can be used to compare magnitudes or quantities.
We will find that the order of magnitude of golf balls that fill a home swimming pool is 10^6
In this case, we want to estimate the number of golf balls that would fill a home swimming pool.
We know that the diameter of a golf ball is D = 42.6mm = 0.0426m
And the volume of a sphere of diameter D is:
V = (4/3)*pi*(D/2)^3
where pi = 3.14
Then the volume of a single golf ball is:
V = (4/3)*3.14*( 0.0426m/2)^3 = 0.00004 m^3
Now we need to find the average volume of a home swimming pool, we can use 48 m^3 (an average one) to do the general math.
To find the number of golf balls that enter in that volume, we need to do the quotient between the volume of the pool and the volume of a single ball:
N = (48 m^3)/(0.00004 m^3) = 1,200,000
If we round this to the next order of magnitude: 10^6 (the exponent is the number of digits at the right of the one)
Then the order of magnitude of golf balls that enter in a home swimming pool is 10^6
