Explanation:

⭐《ANSWER》

↪Actually WELCOME to the concept of the FORCE AND PRESSURE

↪Basically here , we are DEALING with the Normal pressure exerted by a object ( square) on its RESPECTIVE base,

↪Since here , the Object dimension is a SQAURE , so we get as ,

〽Pressure = Force / AREA ,

↪Since here , the pressure is normal to base , also the force is normal to base , thus

↪Force = MG ( g = acceleration due to gravity = 10 m/s^2)

↪so we get as ,

↪F = (0.75)(10)

↪F = 7.5 N

↪now the base area , will be as ,

↪Area = (side)^2

↪Area = (0.1)^2 m^2

↪Area = 0.01 m^2

↪so now here ,

↪PRESSURE = 7.5/0.01

〽P = 750 pa

↪Since here , the SI UNIT of pressure is N/m^2 or Pascals or Pa

↪so we get as ,

⭐PRESSURE ON THE BASE = 750 Pa

Answer:

Representing Free FALL by Position-Time Graphs

A position versus time graph for a free-falling object is shown below.

Observe that the line on the graph curves. As learned earlier, a curved line on a position versus time graph signifies an accelerated motion. Since a free-falling object is undergoing an acceleration (g = 9.8 m/s/s), it WOULD be expected that its position-time graph would be curved. A further look at the position-time graph reveals that the object starts with a small velocity (slow) and finishes with a LARGE velocity (fast). Since the SLOPE of any position vs. time graph is the velocity of the object (as learned in Lesson 3), the small initial slope indicates a small initial velocity and the large final slope indicates a large final velocity. FINALLY, the negative slope of the line indicates a negative (i.e., downward) velocity

Explanation:

23 B the ENERGY NEITHER be CREATED and nor be DESTROYED

Answer:-

The theory of relativity usually encompasses TWO interrelated theories by Albert Einstein: special relativity and general relativity. Special relativity APPLIES to elementary PARTICLES and their INTERACTIONS, describing all their physical phenomena EXCEPT gravity. General relativity is a theory of space and time.The central idea of general relativity is that space and time are two aspects of spacetime. Spacetime is curved when there is gravity, matter, energy, and momentum.

all NUMERICAL

Answer:

EXPLANATION:

u = 25m/s, v = 0, t = 5 s, m = 180 kg

pi = mu = 180 x 25

      4500 kg m / s

pf = my

   = 180 x 0

   = 0 kgm /s

pf - pi = 0 - 4500

         = -4500 kg m / s

Hence, the change in momentum is -4500 kg m/s.

Explanation:

ANSWER:

Explanation:

Radius of CURVATURE of the convex mirror R = 3 m

Focal length of the convex mirror f = R/2 = 1.5 m  (positive for convex mirror)

Object (bus) DISTANCE u = − 5 m

IMAGE distance v = ?

Mirror formula is: 1/f = 1/v + 1/u

                             1/1.5 = 1/v + 1/(−5)

1/v = 1/1.5 + 1/5

     = (5 + 1.5)/(5 x 1.5) = 6.5/7.5

v = 7.5/6.5

  = 1.15 m

Position of the image is at 1.15 m behind the mirror

Answer:

B travelled farther than car A

Explanation:

SPEED of A=54km/h

=15m/s

Speed of B= 36km/h

=10m/s

After PLOTTING the GRAPHS,

Distance travelled by A= 1/2*15*5 m

= 37.5 m

Distance travelled by B= 1/2*10*10 m

= 50 m

conclusion: B travelled farther than A (after applying brakes).

Answer:

MATTER can change from one FORM to other form i.e from solids to liquids to GASES. ... Matter can be changed from one state to another by changing temperature or pressure. Change in state of water. When heat energy is supplied to ICE it changes into water and then to vapor.

ELECTRIC polarisation MAY be DEFINED as the relative shift of positive and negative CHARGES under the influence of an external electric field. It can also be defined as the electric dipole moment per unit volume.P = p/V = q * 2a / VTherefore, its unit would be C/m^2.

Hey mate ☺️

BOILING is the process by which a liquid turns into a vapor when it is heated to its boiling POINT. The CHANGE from a liquid phase to a gaseous phase occurs when the vapor pressure of the liquid is equal to the ATMOSPHERIC pressure exerted on the liquid.

I HOPE it helps you ☺️ ✌️ ✌️

BUDDY all forces NEED MAGNITUDE as well as direction. Since force in itself is a vector quantity. So all types of forces INDISCRIMINATELY are vector quantity.

Answer:

Explanation:

To calculate the resistance of the wire we need the data

1km=1000m

And 5mm=5*10^(-3)

And resistivity of nichrome is 100*10^-6 OHM m

Thus we KNOW that resistance of a substance is resistivity per unit area multiplied by LENGTH

Now resistence(R)=[(100*10^-6)*1000]/(pie*r^2)

Hence resistence(R)=0.1/(3.14*5*10^-3)

Resistence (R)=6.36ohm

Thus now we know that the resistance of nichrome is 6.36 ohm ..

We used the same length and diameter because it is given in the qustn that all the values are same as that of ALUMINIUM hence used the same

Answer:

1.1 cm and -10.7 cm is the correct answer.

LIGHT bulb's image position = 1.1cm

Diameter of light bulb = -10.7cm

Explanation:

Given data :

A CONVEX MIRROR is given.

Focal length = 13 cm

diameter = 6 cm

Height = 60cm

To find:

light bulb's image position and diameter

Solution

1/f = 1/d1 + 1/d2

1/d1 = 1/f - 1/d2

= 1/(-13) - 1/ 60

= -0. 0769 - 0.0166

= -10 cm

We know that,

h2/h1 = - d1/d2

h2 = -d1*h1/d2

= -10.7*6/60

= -64. 2/60

= 1.07cm

=1.1 cm

Hence,

1.1 cm and -10.7 cm is the correct answer.

light bulb's image position = 1.1cm

Diameter of light bulb = -10.7cm

⭐《ANSWER》

↪Actually welcome to the concept of the PROJECTILE MOTION !

↪basically we KNOW that , in the case of the projectiles, the motion PATH or the TRAJECTORY is a Parabolic Function .

↪Also we know that ,

↪The time of flight in the projectile Motion is given as ,

〽T = 2u Sin ⊙ / g

Now here , we given as , U = 392 m/s , ⊙ = 60°

so substituting we get as ,

T = 2 ( 392) Sin 60° / 10

so we get as ,

T = 2*root3/2 *(392) ÷ 10

T = 392*ROOT 3/10 = 67.8

〽⭐so here , the time of flight is , T = 67.8 seconds

Now also here ,

↪RANGE is given as ,

〽R = u^2 Sin2⊙ / g

so we get as ,

R = (392)^2 *1/2 ÷ 10

〽⭐R = 76832/10 = 7683.2 mtrs

↪Now here , the MAXIMUM HEIGHT is given as ,

〽H = u^2 sin^2 ⊙ / 2g

so we get as ,

H = (392)^2 Sin^2 (60) / 2 (10)

H = 153664 * (root3/2)^2 / 20

H = 153664 * (3/4) /20

H = 115248 /20

〽⭐H = 5762.4 mtrs
