Answer:

Let No be initial no of atoms

N = N0 / 2      after 1 half-life

N = N0 / 4     after 2 half-lives

So after 2 half-lives 20 of the 80 atoms remain

the position that has least kinetic energy is option D

Answer:

the right answer is option 2

Explanation:

If an object is placed in front of a plane mirror, the size of the object remains same. This is the property of plane mirror. So the height of the object will be 10cm only.

The image position in the plane mirror is 5 cm.

The ratio of the height of the formed image to the height of the object is used to define the magnification created by the mirror.

Here,

Position of the object, u = -10 cm

Height of the object, h = 10 cm

We know that magnification produced by a plane mirror is 1.

So,

Magnification, m = -v/u

1 = -v/u

Therefore, image distance,

v = -u

v = 5 cm

Hence,

The image position in the plane mirror is 5 cm.

Answer:

RT = 54 Ohms

Explanation:

Given the following data;

Resistance = 18 Ohms

Voltage = 12 Volts

To find the equivalent resistance (RT) of the circuit;

For a series connection, the formula is;

RT = R1 + R2 + R3

RT = 18 + 18 + 18

RT = 54 Ohms

Or

RT = 3*R

RT = 3 * 18

RT = 54 Ohms

Actually Welcome to the concept of Net force on a body.

We know that net force on a body is the force that is calculated from all direction and added , if there is any force remained at last, then the forces are unbalanced,

and if the net force on a body is Zero, then it is a balanced force,

here,

Force to left on skier = 50 N

Force to right on skier = 40 N

hence the net force = left force - right force

Net force = 50 - 40 ==> 10 N

hence the Net force is 10 N in the left direction of the skier.

Answer:

A and C are 180 deg out of phase (opposite points on a 360 deg wave)

The two points on the periodic wave  which are 180 degrees out of phase are point A and Point C.

The two points of a wave is said to be out of phase when they show up or down motion at different times.

If a point on the wave, say (X) is reached to the maximum or minimum point before the other point. Then these two points are said to be out of phase.

Also, when the points are 180 degree apart from each other. Which means if a point is in the crest of the wave and other is on the through.

The diagram below shows a periodic wave. In this diagram,

Hence, the two points on the periodic wave  which are 180 degrees out of phase are point A and Point C.

Answer:

1. Icy

This is so because the icy surface will be slippery due to ice and water residue on it. Not only the stone, anything that goes on the icy surface is likely to slip. There won't be much friction offered by the surface.

If we talk about the sandy surface, the stone won't go far and will be stopped at the nearest point possible and it's also possible that the stone will settle down in the surface.

The dry and cemented surfaces will cause friction when the stone will be thrown on them, which will stop the stone from going far away.

2. Streamline is the body shape which offers very little resistance to the flow of air.

Answer:

W = 0 J

Explanation:

The amount of work done by gas at constant pressure is given by the following formula:

[tex]W = P\Delta V[/tex]

where,

W = Work done by the gas

P = Pressure of the gas

ΔV = Change in the volume of the gas

Since the volume of the gas is constant. Therefore, there is no change in the volume of the gas:

[tex]W = P(0\ m^3)\\[/tex]

W = 0 J

Answer:

I = 1.36 x 10⁻⁴ W/m²

Explanation:

The intensity of the sound produced by the Elephant can be calculated by using the following formula:

[tex]I = \frac{P}{A} \\\\[/tex]

where,

I = Intensity of sound = ?

P = power of sound = 0.45 W

A = area = πr² = π(32.5 m)² = 3318.3 m²

Therefore,

[tex]I = \frac{0.45\ W}{3318.3\ m^2} \\\\[/tex]

Answer:

ncandescent solids emit continuous spectra; incandescent gases emit bright-line spectra.

Explanation:

Materials when heated emit a continuous spectrum with all wavelengths.

Hot gas gases emit a spectrum that depends on the transitions between atomic states, therefore it is a discrete spectrum.

When reviewing the answers, the correct one is:

ncandescent solids emit continuous spectra; incandescent gases emit bright-line spectra.

Explanation:

Answer:

Explanation:

Here, we are asked to calculate the average speed in km/minute.

As we know that,

Here,

→ Total distance = 10 km + 10 km

→ Total distance = 20 km

→ Total time = 8 minutes + 2 minutes

→ Total time = 10 minutes

Substitute the values in the formula of average speed,

→ Average speed = Total distance ÷ Total time taken

→ Average speed = 20km ÷ 10 minutes

Answer:

The collision is inelastic

Explanation:

There are two kinds of collision; elastic collision and inelastic collision. In an elastic collision, both momentum and kinetic energy are conserved.

However, in an inelastic collision, kinetic energy is not conserved. So, when the bumper of two cars collide, the cars come to a stop because the collision is inelastic.
