Answer:

49 because CRITICAL angle of WATER is 48 so it will not be TOTALLY internally REFLECTED

Answer:

Explanation:

Let v1 and v2 be the velocities of the first and second balls after the removal of the uniform electric field. By HYPOTHESIS, the angle between the velocity v1 and the initial velocity V is 60°. Therefore, the change in the momentum of the first ball is

Δp1 = q1 E = Δt = m1v sin60

Here we use the condition that v1 = v/2, which IMPLIES that the change in the momentum Δp1 of the first ball OCCURS in a direction perpendicular to the direction of its velocity v1

Since E || Δp1 and the direction of variation of the second ball momentum is parallel to the direction of Δp1, we obtain for the velocity of the second ball (it can easily be SEEN that the charges on the balls have the same sign)

V2 = vt an30 = v/√3

The corresponding change in the momentum of the second ball is

Δp2 = q2 E Δt = m2V/cos 30

Hence we obtain

q1/q2 = m1 sin60/m2/cos 30

q2/m2 = 4/3 * q1/m1 = 4/4 k1

Be SAFE

The frequency of the transverse wave is as follows:

Frequency = SPEED / Wavelength

• In case of a STRING, the frequency is denoted by:

        F = 1/2L √(T/M)

• Here, f is the frequency of transverse vibrations in the stretched string, L is the length of the string, T is the tension in the string, and M is the mass of the string.

• The frequency of the transverse wave in a stretched string is INVERSELY proportional to the length of the string.

ANSWER:

The HEAT will not be transpoted from neither the water or the ball.Because the TEMPERATURE of both the ball and water is same, IE, 40°C.

Explanation:

The collection of seven Indian musicsl nodes in called as SAPTAK

Saptak. Saptak means "gamut" or "the series of seven notes". It denotes the set of swaras Sa, Re, Ga, Ma, PA, Dha, and Ni, which COMPRISE a musical scale in Indian classical music. In Sanskrit, saptak LITERALLY means "containing seven" and is derived from the Sanskrit word sapta which means "seven"

Answer:

The real EARTH (the planet you are PROBABLY standing on) is electrically neutral. This MEANS that it has the same NUMBER of electrons and protons, so their charges cancel out overall. Scientifically, we describe this by saying that the Earth has an Electric POTENTIAL of zero.

I don't know the real ANSWER but THINK the sinuisoidal wave like a pendulum (basically both are the same, since pendulum also has a sin or cos wave).

in a pendulum,

we can see VELOCITY maximum at its equilibrium POSITION or zero point and minimum at its peak position.

All transverse waves are basically same. you can use this principle in many places.

Thankyou

DISPLACEMENT is the aerial DISTANCE between the start and end POINT. So it covers three quarters which means the displacement is the length of the HYPOTENUES of the right angled triangle with sides r.  

Answer:

Speed = 10m/s.

Speed = 36km/hour.

Explanation:

GIVEN :

Distance = 3km=3000m

TIME = 5min = 300 sec

Speed = Distance / time

= 3000/300

= 10m/s

Time = 5min= 1/12 hour

Speed = Distance / time

= 3/(1/12)

= 36km/hour

Answer:

• The body's mass (M) will be 5 KG.
• The body's WEIGHT (W) will be zero.

Given:

1. Mass of the body (M) = 5 Kg

Explanation:

As we know the Mass is a fundamental quantity which is universally constant. i.e. the value of mass will be constant at every point on this universe.

So, If the Body WEIGHS 5 Kg on the surface of earth then it weighs 5 Kg on the center of the earth.

∴ The body's mass (M) will be 5 Kg at the center of the earth.

From the Formula we know,

Now,

Substituting the values,

MULTIPLYING by Mass on both sides.

∴ The body's weight (W) will be zero at the center of the earth.

Note:

• The body is taken to the center of the earth the depth equals to the radius of the earth. So, we took d = R.

Explanation:

Refraction. Light waves change speed when they pass across the boundary between two substances with a DIFFERENT DENSITY, such as air and glass. This causes them to change DIRECTION, an effect called refraction. My personal opinion is that light does not move SLOWER through matter, it travels through more space.

Answer:

Explanation:

retardation = -ACCELERATION

                   = -(final velocity - INITIAL velocity)/TIME

                  = -(5.5 - 22.2)/6 [km/hr CONVERTED to m/s]

                 =-(-16.7)/6

                  = -(-2.78)

                 = 2.78 m/s^2

The electric field of a point CHARGE can be OBTAINED from Coulomb's law:

The electric field from any number of point charges can be obtained from a VECTOR sum of the individual FIELDS. A positive number is taken to be an outward field; the field of a negative charge is TOWARD it.

This electric field expression can also be obtained by applying Gauss' law.

Answer:

1.65m/s

Explanation:

INITIAL velocity of TRAIN = 40km/h

= 40*1000/60*60

= 11.11 m/s

final velocity of train = 70 km/h

= 70*1000/60*60

= 19.4 m/s

time taken by train = 5sec

acceleration (a) = v-u/t

= 19.4 - 11.1/5

= 8.3/5

= 1.65 m/s

Explanation:

A multimeter or a multitester, ALSO known as a VOM (volt-ohm-milliammeter), is an electronic measuring instrument that combines several measurement functions in ONE unit. A typical multimeter can measure voltage, current, and resistance. Analog MULTIMETERS use a microammeter with a MOVING pointer to display readings.

Explanation:

Escape VELOCITY is the speed that an object needs to be traveling to break free of a PLANET or moon's gravity well and LEAVE it without further propulsion. ... On the other hand, the escape velocity for JUPITER would be many times that of Earth's because Jupiter is so HUGE and has so much gravity.

Explanation:

The ionosphere is the layer of atmosphere from 30 to 600 miles above the earth's surface that ASSISTS in long DISTANCE radio communication.
