A sphere and a cylinder are of same height. Radius of sphere is 7cm. find the volume of cylinder if radius of base of cylinder and radius of sphere are equal.​

Answer»

Step-by-step explanation:

∏*r^2*h

V=3.14159*7^2*14

V=3.14159*49*14

V=3.14159*686

V=2155.13074 cubic CM, or...

V=(22/7)(7^2)(14) (22/7 is an approximation for pi)

V=(22/7)(49)(14)

V=(22)(7)(14)

V=(22)(98)

V=2156 cubic cm

The diagram shows a square with perimeter 20 cm. 3.5 cm Work out the percentage of the area inside that is shaded. 3 cm

Answer»

Given : The diagram shows a square with PERIMETER 20 cm

To Find :  PERCENTAGE of the area inside Square that is shaded

Solution:

Perimeter of Square = 4 * side LENGTH

=> 4 * side length = 20 cm

=> Side length = 5 cm

Area of Square = 5 * 5 = 25 cm²

Shaded Area = Area of square - (1/2)*5* (5 - 3)  - (1/2)*5*(5 - 3.5)

= 25  - (1/2)5(2 + 1.5)

= 25  - (1/2)5(3.5)

= 25  - 8.75

= 16.25

percentage of the area inside Square that is shaded = (16.25/25) * 100

= 65 %

percentage of the area inside Square that is shaded = 65

Number of ELECTRONS = 10²¹ electrons

Time taken (t)= 4 mins = 240 s

\Large{\underline{\underline{\bf{To\:Find}}}}

ToFind

Current FLOWING through the CONDUCTOR (I)

\Large{\underline{\underline{\bf{Solution:}}}}

Solution:

→ First we have to find the charge of the conductor.

→ By quantization of charges we know that

q = ne

where E = charge of an electron = 1.6 × 10⁻¹⁹ C

→ Substituting the datas we get,

q = 10²¹ × 1.6 × 10⁻¹⁹

q = 1.6 × 10² C

→ The current flowing through a conductor is given by

I = q/t

→ Substituting the datas we get

I = 1.6 × 10²/240

I = 0.67 ≈ 0.7 A

→ Hence current flowing through the conductor is 0.7 A

\boxed{\bold{Current=0.7\:A}}

Current=0.7A

→ Hence OPTION d is correct.

Answer»

An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the EARTH resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to propel objects and people into the air, and wreak destruction across entire cities. The seismicity, or seismic ACTIVITY, of an area is the frequency, type, and size of earthquakes experienced over a period of time. The WORD tremor is also used for non-earthquake seismic rumbling.

Earthquake epicenters occur mostly along tectonic plate boundaries, and especially on the Pacific Ring of Fire.

Global plate tectonic movement

At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the GROUND. When the epicenter of a large earthquake is located offshore, the seabed may be DISPLACED sufficiently to cause a tsunami. Earthquakes can also trigger landslides and occasionally, volcanic activity.

In its most general sense, the word earthquake is used to describe any seismic event—whether natural or caused by humans—that generates seismic waves. Earthquakes are caused mostly by rupture of geological faults but also by other events such as volcanic activity, landslides, mine blasts, and nuclear tests. An earthquake's point of initial rupture is called its hypocenter or focus. The epicenter is the point at ground level directly above the hypocenter.
