no we can't replace fuse wire by thicker wire because If the fuse wires are thick, the LARGER cross SECTION DECREASES the resistance across the fuse wire. So, even a HIGH current FLOWS through the fuse it doesn't blow out

A balL is thrown with a velocity of 12m/s at an elevation angle of 30 from the top Of a tower with height 61m. Find the time taken by it to reach the ground. At what distance from the foot of the to were will it hit the ground?

Answer»

component of velocity in the vertical-upward direction is,

v=50sin(30

0

)=50×0.5=25m/s

Let the time TAKEN to reach GROUND from initial position be t sec

The acceleration DUE to GRAVITY is, g=10m/s

, in the vertical-downward direction.

and the DISTANCE traveled is, h=70m, in the vertical-downward direction.

So here, h=−vt+

A car traveeling at 20km/hr speeds up to 60km/hr in 6 sec. What is the accelaration

Answer» GIVEN :U>

  • Initial velocity of Car, u = 20 km/h
  • Final velocity of Car, v = 60 km/h
  • time taken for change in velocity, t = 6 sec

To FIND :

  • Acceleration of Car, a =?

Formula required :

  • First equation of motion

     v = u  + a t

[ Where v = final velocity, u = initial velocity, a = acceleration, t = time taken ]

Solution :

CONVERTING Initial and final velocity given in km/h to m/s

→ u = 20 km/h

→ u = 20 × 5/18  m/s

→ u = 100/18  m/s

u = 50/9  m/s

and

→ v = 60 km/h

→ v = 60 × 5/18  m/s

→ v = 300/18  m/s

v = 150/9  m/s

Calculating acceleration of Car

Using first equation of motion

→ v = u + a t

→ 150 / 9 = ( 50 / 9 ) + a ( 6 )

→ 6 a = ( 150 / 9 ) - ( 50 / 9 )

→ 6 a = ( 150 - 50 ) / 9

→ 6 a = 100 / 9

→ a = ( 100 / 9 ) / 6

→ a = 100 / 54

a = 1.851  m/s²

Therefore,

  • Acceleration of Car is 1.851 m/s².

the pressure P¹ is at a curtain depth in river water and P² at the same depth in sea water. state the relationship between P¹ and P ²​

Answer»

ong>Answer:

The density of the sea WATER is GREATER than the density of the river water.

The pressure of river water is p1 and density is d1

while pressure of sea water is p2 and density is d2

We know,

p1 = h1 d1 g ...(1)

p2 = H2 d2 g ...(2)

Given: h1 = h2

Thus, DIVIDING EQUATION (1) by (2), we have,

p1/p2 = d1/d2

As, d2>d1,

p2>p1

Thus, the relation between the pressure at same depth of river water and sea water is given as,

p2>p1.

35.

What are differences between Ac and dc​

Answer»

ong>Explanation:

Direct current (DC) is the flow of electric CHARGE in only ONE DIRECTION. It is the steady state of a constant-voltage circuit. Most well-known applications, however, use a time-varying voltage source. Alternating current (AC) is the flow of electric charge that periodically REVERSES direction.

12. A concave lens has a focal length of 10 cm. An object 2.5 cm high is placed 30 cm from the lens. Determine the position and size of the image. (3)​

Answer» ONG>Answer:

Size and the position of the image is 0.625 and -7.5 cm respectively.

Given-

Focal length of the concave lens is NEGATIVE so f = -10 cm

Object distance from the lens is u = -30 cm

As, we know that

1/f = 1/v - 1/u where f is the focal length, v is the image distance from the lens and u is the object distance from the lens.

By putting the values in the above formula we get -

v = - 7.5 cm

And we know that magnification is EQUALS to HEIGHT of the image to the height of the object.

So, m = v/u = H1/H0

By putting the values we get -

H1/2.5 = -7.5/ -30

H1= 0.625

A body is dropped from a height . IT moves a distence of 24.5 meter in the last secound hitting the ground . find the height from which it was dropped?

Answer» ONG>ANSWER:

the body is dropped from a height of 19.6 METERS.

Explanation:

By formula Sn=u+a(n-0.5)

u = 0

a = g =9.8

24.5=9.8(n-0.5)

24.5=9.8n-4.9

9.8n=19.6

n=2.

So total time is two seconds.

Height from which it was dropped H is equal to

H=1/2gt^2

H=0.5*9.8*2*2

H=9.8*2

H=19.6

So the body is dropped from a helght of 19.6 meters.
