Answers

Answer 1

Resistor 184Ω has a resistance of.

Explanation of voltage

The "pressure" that drives electricity is known as voltage. Higher voltages cause more electricity to flow to an electronic equipment. The voltage is measured in units called volts (V), and it is symbolized by this unit.

What exactly are voltage and current?

The difference in electric potential between two places is what is referred to as voltage, in other words. Simple electric charge flow rate is known as current. The current, put simply, is the rate at which electrical charge moves across a circuit at a specific location. Volts is the voltage measurement unit used in the SI (V).

a solid cylinder with a mass of 5 kg and a radius of 30 cm is rolling on a flat surface. the cylinder rolls with a speed of 2 m/s. what its kinetic energy?

Answers

The total kinetic energy of a cylinder is 15 J.

Given that, mass = 5 kg

Radius of the cylinder= 30 cm = 30/100 m = 0.3 m

Speed = 2 m/s

Ut = Uk + Ur

where, Uk - translation kinetic energy

Ur - rotational kinetic energy

I is the moment of inertia of the solid cylinder

⇒ 1/2 mv² + 1/2 Iω²

⇒ 1/2 mv² + 1/2 [1/2 m r² * (v/r)²]

⇒ 1/2* 5 * (2)² + 1/2 [1/2* 5 *(0.3)² * (2/0.3)²]

Nuclear decay occurs according to first-order kinetics. What is the half-life of polonium-218 if a sample decays from 55. 4 g to 31. 7 g in 2. 50 minutes?.

Answers

The half-life of polonium-218 if a sample decays from 55. 4 g to 31. 7 g in 2. 50 minutes is 3.5 minutes.

Rate of first order reaction is given by:[tex]kt = 2.303 * log(R'/R)[/tex]

Where , k = rate of reaction

             t= time = 2.5 minutes

             R= final amount = 31.7g

             R'= initial amount = 55.4g

Putting these values in above equation we get k = 0.22

Now half life of a first order reaction is given by: 0.693/k

Putting k= 0.22 , we get half life = 3.5 minutes.

So the half-life of polonium-218 if a sample decays from 55. 4 g to 31. 7 g in 2. 50 minutes is 3.5 minutes.

It is a convex lens that is used to produce a magnified image of an object. The lens is usually mounted in a frame with a handle or wear it like an eyeglasses in front of our eye.

How to calculate, how close can he hold a gem that he is inspecting?
First, let's calculate the focal length of the lens.

f = 1 / P

= 5cm

Convex lens will create a virtual image of a nearby object. Therefore, the image distance is taken as negative, di = -25cm

The position where the gem can be held is calculated with this formula :

1 / f = 1 / do + 1 / di

1 / do = 1 / f - 1 / di

= (1 / 5cm) - (1 / -25cm)

A 90 g mass is attached to one end of a 10-cm-long spring. The other end of the spring is connected to a frictionless pivot on a frictionless, horizontal surface. Spinning the mass around in a circle at 90 rpm causes the spring to stretch to a length of 12 cm.

Answers

The spring constant of the spring is 6.66 N/m.

What is force?

The definition of force in physics is: The push or pull on a massed object changes its velocity.

An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude.

The rotational speed of the 90 g = 0.09 kg mass is: ω = 90 rpm

= 90×2π/60 radian/second.

 = 3π radian/second.

So centripetal force acting on the spring = mω²r

This causes the spring to stretch to a length of 12 cm = 0.12 m.

Hence, spring constant: k = mω²r/0.12 =  0.09×(3π)²×0.10/0.12 N/m = 6.66 N/m.

Hence, the spring constant of the spring is 6.66 N/m.

c. During the third second

Answers

In the first second, a slate drops from the roof of a tall building.

Explain about the seconds?

Second is the standard unit of time in the International System of Units (SI) (s or sec). In decimal form, one cycle of radiation, or 9,192,631,770 (9.192631770 x 109), is equal to one second. This radiation is produced as the cesium-133 atom moves between two levels.

The symbol for a second, or s, is used to denote SI time. It is described as the fixed numerical value of the cesium frequency, vCs, which is the unaltered ground-state hyperfine transition frequency of the cesium 133 atom. The unit Hz, which is equivalent to s-1, is used to express this frequency. The second is the unit of time measurement.

Answers

B- 70 percent of the original strength for intermediate fabric.

What is  Fabric covering?

Fabrics are adaptable and employed in a wide range of industries, including clothing, agriculture, the military, and obviously the healthcare sector. More than you would imagine, specialty textiles are a part of our daily life. These textiles are generally flame resistant, mould and mildew resistant, and particularly treated with antibacterial properties for the healthcare sector. Why, I presume you ask? Because textiles used often in the medical field need to be antimicrobial and stain resistant from the start, this will help prevent bacteria from growing on the fabric surface.

A mover is trying to lift a piano (slowly) up to a second-story apartment. He use a pulley and ropes to decrease the force needed to raise a heavy load (Figure 1) Figure 1 of 1 B mg Part A But for every meter the load is raised, how much rope must be pulled up? Account for this, using energy concepts O For each meter of the load is raised, 2 m of rope must be pulled up. O For each meter of the load is raised, 2.5 m of rope must be pulled up For each meter of the load is raised, 1.5 m of rope must be pulled up. O For each meter of the load is raised, 0.5 m of rope must be pulled up. Submit Request Answer Provide Feedback

Answers

Two metres of rope must be raised in order to move the burden every metre.

Explain why two metres of rope should be raised.

Assuming no dissipative forces are at work over the rope.

The effort is used to draw upward on the rope's free end while the load is hung from the pulley block. The effort required is just half the amount of the load because the load is now suspended from two ropes, each of which is bearing half of the weight.

Hence, two metres of rope must be raised in order to move the burden every metre.

a particle is moving with a constant velocity in the x-direction. when the particle reaches the origin, a constant force is exerted on it in the y-direction. which of the following graphs best shows the path the particle will follow?

Answers

Parabolic Up. Since the force is in the y-direction, the particle will continue to move at a constant speed in the x-direction and accelerate in the y-direction. This creates a parabolic path around y-axis.

Force is the power that changes the motion of an item. A force can purpose an object with mass to alternate its pace. Pressure also can be described intuitively as a push or a pull. A force has both value and path, making it a vector quantity.

Pressure is a push or a pull and it affects us in our daily lives because, without force, people might not be capable of open and near stuff or lifting up their arms or legs.

Variety of Forces :

* Muscular Forces, muscular tissues feature to produce an ensuing force which is referred to as 'muscular force'.

* Frictional Forces, while an item modifications its national motion, 'frictional pressure' acts upon it.

* Carried out pressure.

* Tension force.

* Spring force.

Shown below are the four terrestrial planets of our solar system. Assume that all the planets started out equally hot inside. Rank the planets based on their expected cooling rates, from fastest cooling to slowest cooling.MercuryMarsVenusEarth

Answers

The rank of the terrestrial planets based on their expected cooling rates, from fastest cooling to slowest cooling is as follows -

mercury , Mars, Venus, Earth

Mercury - It is the smallest terrestrial planet in the solar system. It has a thin atmosphere, which causes it to swing between burning and freezing temperatures.

Mars - It is less dense than Earth and has a smaller magnetic field, which is a indication of a solid core rather than a liquid one. Mars is known to have water ice and organics- some of the ingredients for living things.

Venus - It is about the same size as Earth and has a thick, toxic carbon-monoxide (CO) dominated atmosphere that traps heat, making it the hottest planet in the solar system.

Earth - Out of the four terrestrial planets, Earth is the largest and has regular seasons for much of it surface; regions closer to the equator tend to stay warm, while spots closer to the poles are cooler and in the winter, icy.

Therefore, the cooling rate of terrestrial planets is Mars, Earth, Venus, Mercury
