the solid dot shown in the figure below is a pivot point. the board can rotate about the pivot.

Answers

The torque due to perpendicular force will be greatest.

Torque is the measure of the force that can cause an object to rotate about an axis. Force is what causes an object to accelerate in linear kinematics.The unit of torque is Newton–meter (N-m) A simple way to calculate the magnitude of the torque is to first determine the lever arm and then multiply it times the applied force.It is a vector product hence torque also must be a vector. Using vector product notations we can find the direction of torque.

We know that Torque = mass * velocity * sinα

where α = angle between mass and velocity.

For maximum torque, sinα = 1 ; i.e. α = 90°.

So the torque due to perpendicular force will be greatest.

the pulsar in the center of the crab nebula (shown in the figure) is the remnant of a supernova that occurred in a.d. 1054. the current power output of this pulsar is pcrab

Answers

The approximate factor by which the power output of this supernova has declined since its explosion is 2 * 10⁻¹⁰

Rate of power output's decline = Current power output / Initial power output

Current power output = 10²⁸ W

Initial power output = 5 * 10³⁷ W

Rate = 10²⁸ / 5 * 10³⁷

Rate = 2 * 10⁻¹⁰

To convert this rate into a percentage value, multiply this value by 100.

Rate = 2 * 10⁻¹⁰ * 100%

Rate = 2 * 10⁻⁸ %

Therefore, the rate of decline is 2 * 10⁻¹⁰

Answers

The correct sequence will be: A, B, C

Given,

Resistance A = 240 Ω

Resistance B = 192 Ω

Resistance C = 144 Ω

We know that the resistance has relations with Current (I) and Voltage (v)

But to find the work done by the hand,

We will apply the formula of the work,

W = VIt

Replacing V with R/I

Work = (R/I)*I*t

Work= R*t

The time given is same.

Answers

A parallel plate capacitor has a capacitance of C=fracepsilon_0 Ad, where A is the area of the plates and d is the distance between them. 1) If the area of the plates A_1 grows, then A_1>A C_1=fracepsilon_0 A_1d>fracepsilon_0 Ad C_1>C, which means that the capacitance also grows.

2) If the distance between the plates is increased by d_1, the capacitance decreases because d_1>d C_1=fracepsilon_0 Ad_1 fracepsilon_0 Ad C_1C.

3) Since capacitance is directly proportional to plate area, capacitance also increases with plate area.

Because capacitance is inversely proportional to plate separation, capacitance decreases as plate separation increases.

how is einstein's famous equation, e = mc2, important in understanding the sun?

Answers

The correct answer is option D) the Sun generates energy to shine by losing 4 million tonnes of mass each second.

What is sun ?

The Sun, a 4.5 billion year old yellow dwarf star and the centre of our solar system, is a hot, glowing ball of hydrogen and helium. It's about 93 million miles (150 million kilometers) from Earth and it's our solar system's only star. The sun is not a solid mass. It does not have easily identifiable boundaries like rocky planets like Earth. Instead, the sun is composed of layers made up almost entirely of hydrogen and helium.

It explains the fact that the Sun generates energy to shine by losing some 4 million tonnes of mass each second. The "lost" 4 million tonnes is turned to an amount of energy equal to this mass times the speed of light squared.In order to produce the energy we see it produce, the Sun needs to fuse 4 × 1038 protons into helium-4 per second. The upshot of that fusion is that 596 million tonnes of helium-4 are formed with each second that passes, while 4 million tonnes of mass are turned into pure energy via E = mc2.

Answers

The block's acceleration is 3.585 m/s^2, while the cord tension is 17.4 N. depicts two blocks attached by a cord (of minimal mass) that crosses a frictionless pulley.

A block weighs 1.30 kg per m1.

A 2 m2 block weighs 2.8 kg.

Block-block system acceleration = a

T is equal to the cord's tension.

The acceleration of block 1 in our coordinate systems is equal to the acceleration of block 2 in our coordinate systems. So, using a common acceleration, we can express them. These are the motion equations:

T = m1*g - m1*a and M2*g - T

We obtain the equation of motion for the entire system by combining the two equations.

(m1+m2)

*a = m2*g-m1*g

The acceleration is given by the equation a = (m2-m1)*g/(m1+m2), a = (2.8-1.3)9.8/(1.3+2.8), and a = 3.585 m/s2.

The difference between two slits is 0.09m

It can be seen that the separation between two consecutive interference maxima is constant and independent of the order observed.

Considering that the small angle approximation is valid then we have to

                              y1 = (1* 5.10m* d/20) / d

                                y1 = 0.25

                               y2 = (1*5.10m*d/15) / d

Therefore, the first order maximum produced by laser 1 is closer to the central maximum than that the 1st order maximum produced by laser 2.

Answer:B

Explanation:According to newtons 3rd law, the forces must be equivalent

according to this graph, the minimum size of an object that could cause a mass extinction is a little less than _____.

Answers

According to this graph, an object that would cause a mass extinction would need to be at least 10 km is diameter.

What is object and example?

Any word (or pronoun) that forms the subject of a verb or preposition is referred to as an object. There are three categories of items: Straight Thing (e.g., I know him.) Unrelated Item (e.g., Give her the prize.) Prepositional Object (e.g., Sit with them.)

What is object a sentence?

An expression's subject. The subject's verb's action upon a person, place, or thing is typically called the object. As you might expect, looking for the pronoun or the noun that follows the verb is the quickest approach to identify the subject in a simple sentence.

Are these statements about the Fluid mechanics true?
Statement 1: Fluid mechanics is a branch in chemistry that involves study of fluids.
Statement 2: Fluid mechanics can be divided into 2 major categories.
a) True, False
b) True, True
c) False, True
d) False, False

Answers

Announcement 1: Fluid mechanics is a branch of chemistry that involves having a look at fluids:  c) False, True

Fluid mechanics is the branch of physics concerned with the mechanics of fluids and the forces on them. It has programs in an extensive variety of disciplines, such as mechanical, aerospace, civil, chemical, and biomedical engineering, geophysics, oceanography, meteorology, astrophysics, and biology. Fluid mechanics is the look at of the forces of the fluid and the way fluids flow. Fluid mechanics may be divided into parts: fluid statics and fluid dynamics. Fluid statics is the observation of fluids at rest, and fluid dynamics is the study of fluids in motion.

Fluid mechanics is the look at fluid behavior (beverages, gases, blood, and plasmas) at relaxation and in movement. Fluid mechanics has a huge variety of packages in mechanical and chemical engineering, organic structures, and in astrophysics.
