ong>Answer:

Cross product of TWO vectors is ALWAYS a vector quantity.

In vector product, the resulting vector contains a negative sign if the ORDER of vectors is changed.

Direction of   A X B is always perpendicular to the plane containing A and B

Cross product of any two linear vectors is always a null vector

Every SECOND he changes the direction.

When the OBJECT locates at equilibrium position towards POSITIVE , it's VELOCITY is maximum and acceleration takes zero. Explanation: HOPE this ANSWER will help you.

Energy of ONE DAY =Power×Time=400W×8h=3.2KWh

Energy of 30 days =3.2KWh×30=96KWh

So, COST of the energy =96×3=Rs.288

ong>Answer:

TRANSLATION: If an object's speed (velocity) is increasing at a CONSTANT rate then we SAY it has uniform acceleration. The rate of acceleration is constant. If a CAR speeds up then slows down then speeds up it doesn't have uniform acceleration.

ong>Answer:

1. Ohm's Law states that the current flowing in a circuit is directly proportional to the applied potential difference and inversely proportional to the RESISTANCE in the circuit. In other words by doubling the voltage across a circuit the current will also double.

2. REFRACTIVE index, also CALLED index of refraction, measure of the bending of a ray of light when passing from one medium into another. ... Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v.

3. State SNELL's law of refraction of light. ... Statement: It states that “The RATIO of the sine of the angle of incidence to the sine of the angle of refraction is constant for a given pair of media and given wavelength of light.” The constant in law is called refractive index and denoted by the letter 'n'.

@Ask The MASTER

ong>Explanation:

Consider a body having initial velocity 'U'. Suppose it is SUBJECTED to a UNIFORM acceleration 'a' so that after time 't' its final velocity becomes 'v'. Now, from the DEFINITION of acceleration we know that:

Acceleration =

Time taken

Change in velocity

or Acceleration =

time taken

Final velocity- Initial velocity

So, a=

t

v−u

at=v−u

and, v=u+at

where v= final velocity of the body

u= initial velocity of the body

a= acceleration

and t= time taken

ong>ANSWER:

Yes.

ong>ANSWER:

In one dimensional motion, the “deceleration” is DEFINED as the acceleration which is OPPOSITE to the VELOCITY.

mass DEFECT(m)=2KG

speed of light in vacuum(c)=3×10^8 m/S

Energy released=mc^2=2×3×10^8 J

=6×10^8 Jmass defect(m)=2kg

speed of light in vacuum(c)=3×10^8 m/S

Energy released=mc^2=2×3×10^8 J

=6×10^8 J

K = 1 2 I ω 2 . We see from this equation that the kinetic energy of a rotating rigid body is directly proportional to the moment of INERTIA and the square of the angular velocity. This is EXPLOITED in flywheel energy-storage devices, which are designed to store large amounts of ROTATIONAL kinetic energy.

ong>Answer:

When A is greater than B in MASS, then A falls faster than B. A NEEDS greater force to be moved than B and so on but one thing your are IDIOT.

IC :- Rotational Dynamics

• Moment of inertia (I) = 200 kg-m²
• Weight of the OBJECT (F) = 19.6 N
• Radius of gyration (K) = ?

To CALCULATE the radius of gyration about an axis we will use the given below formula :

But here first we need to find the mass of the object. So, let's first find the mass of the object

Hence, the mass (M) of the object is 2 kg. Now, let's find the radius of gyration (K).

ong>Answer:

Case \(I:\)

initial VELOCITY,\(u=0\)

final velocity,\(v=10\ m/s\)

time, \(t=25\ s\)

From the EQUATION of MOTION, we have

\(v=u+at\)

where \(a\) is ACCELERATION.

\(10=0+a(25)\)

\(a=\frac{10}{25}=\frac{2}{5}=0.4\ m/s^2\)

Case \(II\)

initial velocity,\(u=10\ m/s\)

final velocity, \(v=0\)

time, \(t=50\ s\)

From the equation of motion, we have

\(v=u+at\)

where \(a\) is acceleration.

\(0=10+a\times50\)

\(a=\frac{-10}{50}=-0.2m/s^2\)

Let \(s\) be the TOTAL distance covered by the Anil.

From the equation of motion, we have

\(s = ut+\frac{1}{2} at^2\)

\(s=10 \times50 + \frac{1}{2}\times (-0.2)\times(50)^2\)

\(s = 500+250\)

\(s = 750\ m\)

ATP (Adenosine tri-phosphate) is an important molecule found in all LIVING things. THINK of it as the “ENERGY currency” of the cell. If a cell needs to spend energy to accomplish a TASK, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate.
