CURRENT (Denoted by I )

Has a relation formula with CHARGE defined as

I=Q/T

where Q is charge (S.I. unit C [Coulomb])

and T is time (S.I. unit s [SECOND])

So from here we DERIVE unit of current to be

Coulomb/second

But it has a different fundamental unit

Ampere

After Andre Marie Ampere

Definition:

The flow of charge per unit time is defined as current.

Dimensional formula:

Electricity is one of the IMPORTANT types of energy and POWER that we use in our DAILY lives. It is an essential part of modern life and the ECONOMY of a country depends on it. We use electricity for residential, industrial, commercial, transport etc. The electric power that we use at our residence is generated at a distant power plant.

VENTILATORS are provided in the rooms at the top of the roofs, just below the roofs because if the air inside the room GETS hot thehot air RISES up and FLOW through these ventilators and THUS cool air remains at bottom so that to relive in hot sumers.

The TOTAL FORCE ACQUIRED by an OBJECT or a BODY.

a ball is thrown vertically upward from TOP of the TOWER with speed of 100m/s it strike the pond near the base of the tower after 25 sec.

initial velocity of ball, u = 100m/s

TIME taken to strike the pond near the base of the tower , t = 25sec.

Let height of tower is H.

when ball is thrown upward, acceleration due to gravity acting on it, due to this after some time ball becomes rest.

let at h height from the top of tower ball becomes rest.

now using formula, v² = u² + 2as

or, 0 = (100)² + 2(-10) × h

or, h = 500m ....(1)

and time taken to reach h = 500m

v = u + at

or, 0 = 100 - 10t => t = 10s

hence, (25 - 10)s = 15s require to fall the ground

now ball is LOCATED at S = (H + 500)m

where velocity of ball , u = 0

and time taken to fall the ground, t = 15s

using formula, s = ut + 1/2 at²

or, -(H + 500) = 0 + 1/2 (-10) × (15)²

or, H + 500 = 5 × 225 = 1125

or, H = 1125 - 500 = 625m

hence, height of tower is 625m

The INERTIA of BODY don't CHANGE.

Mantle convection is the slow creeping motion of Earth's ROCKY mantle caused by convection currents CARRYING HEAT from the INTERIOR of the earth to the surface. It is one of 3 driving FORCES that causes tectonic plates to move around the Earth's surface.

Hey...
Here is your answer...

SOLVED it in the copy for your better concept.

Hope it helps.
Have a GOOD DAY.

1hp=746watts in this WAY hp is related to SI unit of POWER

after completeing three quaters of a CIRCLE

by PYTHAGORAS threorem a RIGHT angled triangle is formed so displacement=underoot(2) *R ........

THE CHANGE IN DISPLACEMENT HAPPENING PER SECOND IS CALLED VELOCITY

PLEASE MARK AS BRAINLIEST

The COPPER bottom of the vessel makes the vessel low heat capacity as copper has low specific heat capacity and it absorbs the heat QUICKLY so it is EASY to cook in itand wood is a NON conductor of heat MEANS it has high specific heat capacity which helps in holding the hot vessel as it doesn't gain the heat quickly

same velocitry in OPPOSITE DIRECTION so that TOTAL MOMENTUM is CONSERVED.........

v1=-v2.........

A REGION of space having a gravitational field so intense that no matter or radiation can escape.

informal

a place where money or lost items apparently DISAPPEAR without TRACE.

First add two forces we will get 2i+3j+4k as resultant FORCE. And DISPLACEMENT=5i+4j+3k-(2i+3j+4k)=3i+j-k. Do dot product of force and displacement to FIND Work .Work=(2i+3j+4k).(3i+j-k)=
6+3-4=5 J . So (A) 5 J is the correct OPTION.

In GENERAL before one attempts to balance the masses in a chemical reaction is necessary to determine first if there is a change of OXIDATION state  (* ) from the reactants to the product of the reaction..If there is a change the total units of oxidation-reduction must be first balanced before balancing the mass.

In this case :   N2 + H2 = NH3   N2 is in the 0 oxidation state ( uncombined) and as a product in NH3

is in the -3 oxidation state ( because it is combined with 3H+) this means  there is a reduction of 3 units per N atom  and a total of 6 for the 2 atoms reacting.. now H is in the 0 oxidation state also and is oxidized to the +1 state in the product NH3 and since there are 2 of them the total oxidation units are2.

  A reaction requires the number of oxidation units to be equal to the reduction units. We can obtain this by using 3 molecules of H . If we use 3H2,the equation will be balanced in redox units.

 

 

              N2+ 3H2  = NH3

 

Now the mass balance.

There are 2 N on the left and only one on the right. a coefficient of 2 for NH3 will satisfy the mass requirements  ( 2N,left; 2N right; 6H left; 6H right )

 

                                    N2 + 3H2  = 2 NH3

They will MEET only when they are about to released.

Otherwise,

They will not meet at any POINT during their falls.

Speed is a measure of how quickly an OBJECT moves from ONE place to ANOTHER. It is equal to the distance TRAVELED divided by the time. ... To find the speed, distance is over time in the triangle, so speed is distance divided by time.

We first get the ACCELERATION of the particle.

Acceleration = change in speed / change in time

This equals to :

20 - 10 = 10

10 / 2 = 5m/s²

The speed after 3 SECONDS is :

(V - 10) / 3 = 5

V - 10 = 15

V = 25 m / s

A. 10 kmph

B. 35 kmph

c. PART B to C

d. part C to D

e. 60 × 8 = 480 km

When we PASS ALPHA RAYS through them

Hii..
Here is your ANSWER..

Solution:-
Initial velocity(u)=10m/s
Final velocity(v)=20m/s
Time =5 sec

Now,
We'll FIND Acceleration then will find the answer by using EQUATION:-


Now,
Velocity before 3 SECOND=

=>6m/s

Hope it helps uh....✌️✌️✌️

Mercury Facts===. 1)Mercury is the closest planet to the Sun

2) and is also the SMALLEST of the eight planets in our solar system.

3)For every 2 orbits of the Sun, which takes around 88 Earth days, Mercury COMPLETES three rotations of its axis.

4) It is gravitationally LOCKED and this rotation is unique to the solar system.
5)mercury dont have any moon ring .

In which CLASS are you in

In a computer, the Advanced Configuration and Power Interface (ACPI) provides an open standard that operating systems can use to DISCOVER and configure computer hardwarecomponents, to perform power managementby (for example) putting unused components to sleep, and to perform status monitoring. First released in December 1996, ACPI aims to replace Advanced Power Management(APM), the MultiProcessor Specification, and the Plug and Play BIOS (PnP) Specification.[1]ACPI brings the power management under the control of the operating system, as opposed to the previous BIOS-centric system that RELIED on platform-specific firmware to determine power management and configuration policies.[2] The specification is central to the Operating System-directed configuration and Power Management(OSPM) system, an implementation for ACPI which removes DEVICE management responsibilities from legacy firmware interfaces via a UI.

Internally, ACPI advertises the available components and their functions to theoperating system kernel using instruction lists ("METHODS") provided through the systemfirmware (UNIFIED Extensible Firmware Interface (UEFI) or BIOS), which the kernel parses. ACPI then executes the desired operations (such as the initialization of hardware components) using an embedded minimal virtual machine.

Intel, Microsoft and Toshiba originally developed the standard, while HP, Huawei andPhoenix also participated later. In October 2013 the original developers of the ACPI standard agreed to transfer all assets to theUEFI Forum, in which all future development will take place.[3]
