ong>Answer:

If the universe did begin with a rapid expansion, per the Big Bang THEORY, then life as we know it sprung from nonliving MATTER. ... It proposes that in Earth's prebiotic history, SIMPLE organic matter was EXPOSED to energy in the form of volcanoes and electrical storms.

ong>Explanation:

Alternative Title: Newton's law of universal gravitation. Newton's law of gravitation, STATEMENT that any PARTICLE of MATTER in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the DISTANCE between them.

Answer:

Acceleration:

➤ The rate of change of velocity of a body is called acceleration.

Positive acceleration:

➤ If the velocity of a body is INCREASING with respect to time, then the acceleration is said to be positive.

For EXAMPLE:

• A cyclist moving through a busy street does not have a uniform velocity. The velocity of cyclist may change in magnitude, the direction or both. In such a case the cyclist is said to have an accelerated motion, which is positive as it is moving in forward direction or the velocity of the body is increasing with respect to time.

Negative acceleration:

➤ If the velocity of the body is decreasing with respect to time, the acceleration is said to be negative. It is also called deceleration or retardation.

For example:

• When we throw the ball UPWARDS i.e, in the upward direction, then the negative acceleration acts on it. As the velocity of an object is negative. Therefore the acceleration is negative.

Unit of acceleration:

In SI system it is expressed in m/s².

N.B - It must be remembered that acceleration is a vector quantity, as it is expressed in magnitude and direction. It is generally represented by letter 'a'.

Give one similarity and one dissimilarity between the GRAPHS:

Ans.

Similarity:

• Both the graphs show uniform acceleration that is the body describes equal change in velocity in equal intervals of time.

Dissimilarity:

• In the first graph, the object starts from the rest. Therefore the initial velocity is zero, v = 0.
• In the second graph, the object does not start from rest, as the object possesses some velocity when it starts that is it possesses some initial velocity, v ≠ 0.

The invisible area AROUND a magnet which attracts another object is CALLED a magnetic field. Magnetic objects (such as paperclips) will get pulled towards the magnet if they are PLACED in this field. ... The magnetic field is strongest at the poles. You can see this because the iron filings cluster at these points.

It will be UNIFORM MOTION .

rong>Answer:

Let's understand about power first!

It is common experience that different persons complete a given work in different times. A person doing work quickly is said to be stronger but a person who does some work in a longer time is said to be weaker. In this context, we define the term power, which is a measure of rate of doing work.

Power:

The power of a person/machine/system is defined as its rate of doing work.

If W work is done in the time t, then the power P is given as:

✭ Power, P = Work, W/ Time, t ✭

Let's come to QUESTION now...

As we are provided with the work and time of both men A and B. We will find the power of both men A and B separately and then COMPARE them to find out who has more power. After that we will find out the ratio of their powers.

Let's find out...✧

a.)

➛ Work done by man A, W = 450 J

➛ Time taken, t = 5s

✭ Power, P = Work, W/ Time, t ✭

Putting the VALUES in the formula, we have:

➛ P = 450/5

➛ P = 90 W

∴ Power of man A = 90 W

➛ Work done by man A, W = 240 J

➛ Time taken, t = 5s

✭ Power, P = Work, W/ Time, t ✭

Putting the values in the formula, we have:

➛ P = 240/3

➛ P = 80 W

∴ Power of man B = 80 W

Comparing the powers of both we find that,

90 W > 80 W

Power of man A > Power of man B

∴ Man A has more power.

b.)

➛ The ratio of the power delivered by A to that delivered by B = Power of man A/Power of man B

➛ The ratio of the power delivered by A to that delivered by B = 90/80

➛ The ratio of the power delivered by A to that delivered by B = 9/8

➛ The ratio of the power delivered by A to that delivered by B = 9:8

∴ The ratio of the power delivered by A to that delivered by B is 9:8

atoms doesn't have WALLS but they have NUCLEUS which contains NEUTRON and proton

ong>Explanation:

The law of constant proportions states that chemical compounds are made up of elements that are present in a FIXED RATIO by mass. This IMPLIES that any pure sample of a COMPOUND, no matter the source, will always consist of the same elements that are present in the same ratio by mass.

SINCE the REFRACTIVE index of diamond is more, hence the speed of LIGHT is lesser in diamond. LET speed of light in water vevw and in diamond bevd. n = (Vwc) ÷ (Vdc) = Inverse Ratio of refractive index of water and diamond. n=2.421.33 = 1.82 (approx.)

In the middle of every atom is the NUCLEUS. The nucleus contains TWO types of subatomic particles, PROTONS and neutrons. The protons have a positive electrical charge and the neutrons have no electrical charge. A third TYPE of subatomic particle, electrons, move around the nucleus.

Answer:

a.)

✭ F = ma ✭

Where,

• F is the force applied by the man in lifting the box.
• m is the mass of the box.
• a is the ACCELERATION due to gravity.

Putting the values in the formula, we have:

➥ F = 250 × 10

➥ F = 2500 N

Given:

Displacement in the direction of force of lifting the box ( s ) = 1 m

✭ W = F × s

Where,

• W is the work done by the persons in lifting the box.
• F is the force applied by the man in lifting the box.
• s is the displacement in the direction of force of lifting the box.

Putting the values in the formula, we have:

➥ W = 2500 × 1

➥ W = 2500 J

∴ The work done by the persons in lifting the box = 2500 J

b.)

➥ Zero work is done for just holding the box. As there is no displacement while just holding the box, that is there is no distance covered between the initial and the final position, therefore there is no work done or in other words you can SAY that work done is zero.

c.)

➥ In ORDER to hold the box men is applying a force against the gravity. The men are applying equal and opposite force to the gravitational force, which is acting on the box. So while applying the force, their muscles are are involved or you can say muscular effort is involved, so they feel tired while holding the box.

ong>Explanation:

Net force is the vector sum of FORCES acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion. It gives the particle the same ACCELERATION as all those actual forces together as DESCRIBED by NEWTON's second law of motion.

Explanation:

The characteristic impedance of free space is equal to the square root of the RATIO of permeability of free space (in HENRYS per METER) to the permittivity of free space (in farads per meter). It WORKS out to about 377 Ω, and that is the characteristic impedance of the UNIVERSE.

ong>Answer:

1. MASS (m) = 300 g

= 300/1000 kg

= 0.3 kg

Volume (v) = 400 cm³

= 400/1000000 m³

= 0.0004 m³

a. DENSITY in C.G.S UNIT = Mass/Volume

= 300/400 g/cm³

= 0.75 g/cm³

b. Density in S.I Unit = Mass/Volume

= 0.3/0.0004 kg/m³

= 750 kg/m³

2. Given,

Mass (m) = 5000 g

Density of wood = 0.8 g/cm³

∴ Density = Mass/Volume

= 0.8 = 5000/Volume

= 0.8Volume = 5000

= 6250 cm³ = Volume

I hope this HELPS.

down the group electropositivity increases.

Explanation:

because down the group inner SHELL electron increases. down the group SCREENING effect increases. EFFECTIVE nuclear CHARGE decreases down the group . so size increases .easy to remove the electron .therefore electropositivity increases.

Answers. spin 1/2 fermions (electron, proton, neutron, muon, tau, quarks) have +1 parity (by convention as pointed out in ANNA's comment). The corresponding anti-fermions have -1 parity. Bosons and their anti-particles have the same parity.

Explanation:

No electron is not same as proton

An electron is a negatively charged component of an atom whereas the proton is a positively charged body. The electrons are present outside the nucleus in the ORBITING shells. But the protons along with NEUTRONS form the nucleus of the atom and are present at the CENTER of the atomic nuclei
