Pole is the answer.

Actually when we measure, we use metre scale and thread. But since option doesn't have it, so Pole is the answer . Because all curved surfaces has a pole . So, we can directly measure around it.

Hope it helps you

[tex]\boxed{\sf P=I^2R}[/tex]

[tex]\\ \sf\longmapsto I^2=\dfrac{P}{R}[/tex]

[tex]\\ \sf\longmapsto I^2=\dfrac{9.28}{210}[/tex]

[tex]\\ \sf\longmapsto I^2\approx0.04[/tex]

[tex]\\ \sf\longmapsto I\approx\sqrt{0.04}[/tex]

[tex]\\ \sf\longmapsto I\approx\sqrt{\dfrac{4}{100}}[/tex]

[tex]\\ \sf\longmapsto I\approx\dfrac{\sqrt{4}}{\sqrt{100}}[/tex]

[tex]\\ \sf\longmapsto I\approx\dfrac{2}{10}[/tex]

Answer:

[tex]difference \: in \: weight = 150n - 100n = 50n[/tex]

Now,buyantant force

[tex]difference \: in \: weight \: = volume(body) \times density \: of \: water \: \times g[/tex]

so;

[tex]50 = {v}^{b} \times 1 \times {10}^{3} \times 9.8m {s}^{2}[/tex]

[tex] {v}^{b} = \frac{50}{1000 } \times 9.8[/tex]

[tex] = \frac{50}{9800} [/tex]

[tex] = 0.0051[/tex]

Now,

[tex]mass \: in \: air \: = 150n = \frac{150}{9.8kg} [/tex]

[tex]density = \frac{weght}{volume} [/tex]

[tex] = \frac{150}{0.0051} \times 9.8 \\ x = 3000[/tex]

And now,

[tex]specific \: density \: = \frac{density of \: the \: body}{density \: of \: water} [/tex]

[tex] = \frac{3000}{1000} [/tex]

[tex] = 3[/tex]

Hence that,specific density of a given body is 3

Explanation:

(1) Every object moves in a straight line unless acted upon by a force. (2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object's mass. (3) For every action, there is an equal and opposite reaction.

I took the quick check and it’s right.

Answer:

because only two electrons can fit in the first orbit around the nucleus, and each period on the table is organized by number of orbits

There are only two elements in the first period of the periodic table (statement 4) because only two electrons can fit in the first orbit around the nucleus, and each period on the table is organized by the number of orbits

A period is defined as an interval  required for a cycle to repeat itself.

Period 1 has only two elements (hydrogen and helium) as they have electrons in only the 1st energy level or first orbit and each period on the table is organized by the number of orbits or level of energy.

Process:

You multiply 100cm x 50cm x 30cm. The reason you do this is because the "mass" will be the volume of the tank of water. A "small 2" would represent a two dimensional area, whereas the "small 3" would represent a 3 dimensional area.

Answer:

B

Explanation:

The control is something that is meant to not be changed, the control is a comparison of the experimental.

a) An inflated balloon was pressed against a wall after it has been rubbed with a piece of synthetic cloth. It was found that the balloon sticks to the wall. This is because a positive and negative electric charge is produced, therefore the balloon sticks to the wall.

b) When an object is thrown up, it comes back to ground because of gravitational attraction force of earth.

c) Mountaineers suffer nose bleeding at higher altitudes because the oxygen level decreases with increase in altitude, which the body cannot adjust.

d) Foundations of high rise buildings are kept wide because more is the area of contact, less is the pressure efforts. So, foundations are wide so as to decrease the possibility of the building from falling down.

e) Deep sea divers or high altitude fliers wear special suits so as prevent their body from being crushed by the water pressure. Since water pressure is maximum at deep seas and oceans, therefore, more is the risk of being injured.

f) Walls of a dam are thickened near the base so that the dam can handle the kinetic energy pressure and prevent itself from breaking down, which if not, can lead to flooding.

Answer:

A voltage-controlled resistor (VCR) is a three-terminal active device with one input port and two output ports. The input-port voltage controls the value of the resistor between the output ports. VCRs are most often built with field-effect transistors (FETs). Two types of FETs are often used: the JFET and the MOSFET.

Answer:

Assumption: the acceleration of this vehicle is constant until it comes to a stop.

Acceleration: [tex](-2)\; \rm m\cdot s^{-2}[/tex].

The acceleration of this vehicle is negative because the velocity of this vehicle is decreasing over time.

Explanation:

Assume that the acceleration of this vehicle, [tex]a[/tex], is constant. The SUVAT equations would apply.

The time [tex]t[/tex] required for braking is neither given nor required. Hence, make use of the SUVAT equation [tex]v^{2} - u^{2} = 2\, a\, x[/tex] to relate [tex]u[/tex], [tex]v[/tex], [tex]a[/tex], and [tex]x\![/tex].

Rearrange this equation to find an expression for [tex]a[/tex], the acceleration of this vehicle:

[tex]\begin{aligned}a &= \frac{v^{2} - u^{2}}{2\, x} \\ &= \frac{(0\; \rm m\cdot s^{-1})^{2} - (10\; \rm m \cdot s^{-1})^{2}}{2\times (25\; \rm m)} \\ &= \frac{0^{2} - 10^{2}}{2 \times 25}\; \rm m \cdot s^{-2} \\ &= -2\; \rm m\cdot s^{-2}\end{aligned}[/tex].

Acceleration is the rate at which velocity changes over time.

The velocity of the vehicle in this question is getting smaller over time. Hence, the rate of change of the velocity of this vehicle (that is, the acceleration of this vehicle) would be a negative number.
