If the distance of an object is determined from the relation: d = a X + b Y Where: (d) is the distance covered by the body. (a) is a physical quantity which has a dimensions (L T^-1). (b) Is a physical quantity which has a dimensions (L T^-2). So: *

The dimension formula of (X) is T and that of (Y) is T^2.

The dimension formula of (X) is T and that of (Y) is T^-2

The dimension formula of (X) is T^-1 and that of (Y) is T^2.

The dimension formula of (X) is T^-1 and that of (Y) is T^-2.​

Answers

Answer 1

Answer:

The dimension formula of X is T and that of Y is  T^2

Explanation:

                     d = aX + bY is ACTAULLY  [tex]S = V_{i} t + \frac{1}{2} a t^{2}[/tex]

                     so v = LT^-1

                          t = T

                          numerics do not have any dimensional formula so ignore [tex]\frac{1}{2}[/tex]

                          a = LT^-2

                          t = T^2

                         So answer for x is T and y T^2

9500 kgm/s
95000 kgm/s

Answers

Answer:

The answer is 9500 kgm/s

Explanation:

The momentum of an object can be found by using the formula

momentum = mass × velocity

From the question

mass = 950 kg

velocity = 10.0 m/s

We have

momentum = 950 × 10

We have the final answer as

9500 kgm/s

Two statements describe reasons a solar cell must contain semiconductors :

A. Semiconductors form a path for the electrons that are released by the photoelectric effect.

C. Semiconductors serve as a source of electrons to form an electrical current.

What is Photoelectric effect?

Photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation.

When the semiconductor is exposed to light, it absorbs energy and transfers it to the material, due to which energy reaches to negatively charged particle (electron), which allows the electron to flow in the material as electric current .

hence , correct option will be :

A. Semiconductors form a path for the electrons that are released by the photoelectric effect.

C. Semiconductors serve as a source of electrons to form an electrical current.

how far will a 600 kg boat travel in 12 s if there is a constant 900 N force on it and it starts from rest?​

Answers

Answer:

Distance, S = 108 meters.

Explanation:

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

[tex] F = ma[/tex] ............equation 1

Where;

F represents force measured in Newton. m represents the mass of an object measured in kilograms. a represents acceleration measured in meters per seconds square.

Given the following data;

Since the boat is starting from rest, initial velocity, u = 0

Mass, m = 600kg

Time, t = 12s

Force, F = 900N

Substituting into equation 1, we have;

[tex] 900 = 600*a[/tex]

[tex]a = \frac{900}{600}[/tex]

Acceleration, a = 1.5 m/s²

T

To solve for distance, we would use the second equation of motion;

[tex] S = ut + \frac {1}{2}at^{2}[/tex]

Substituting the values into the equation, we have;

[tex] S = 0(12) + \frac {1}{2}*1.5* 12^{2}[/tex]

[tex] S = 0 + 0.75* 144[/tex]

Distance, S = 108m

Therefore, the distance covered by the boat is 108 meters.

Explanation:

Using our knowledge of physics... If we know that the moving man travels 10 meters, has an initial velocity of 0 m/s and an acceleration of 1 m/s, use the equation d = vi t + 1/2 a t^2 to solve for time.

Answers

Answer:

t= 4.5s

Explanation:

vi=0m/s

a= 1m/s

d=10m

10m= 0(t) + 1/2(1m/s)(t^2).    0xt cancels out, 1/2 of 1= .5

10m=  .5m/s(t^2)   Divide both sides by .5

20m= t^2.  Take square root of each side

Silver has a resistance of 0.0198 ohms. What voltage would produce a current of 250 amps?

Answers

Answer:

V= I x R =250 x 0.0198 = 4.95 Volts

Explanation:

The voltage across the resistor is 4.95 Volts.

How do you calculate the voltage?

Given that the resistance is 0.0198 ohms and the current flowing through the silver is 250 amps.

The voltage V across the resistor is the product of the current I flowing through the resistors and resistance R.

[tex]V = IR[/tex]

Substituting the values, we get the voltage.

[tex]V = 250 \times 0.0198[/tex]

[tex]V = 4.95 \;\rm V[/tex]

Hence we can conclude that the voltage across the resistor is 4.95 Volts.

An inclined plane is 10.0 m long and 2.5 m high. What is the mechanical advantage?

Answers

Answer:

MA = 4

Explanation:

In order to solve this problem, we must use the definition of the ideal mechanical advantage, which tells us that it is equal to the relationship of the inclined distance over the height with respect to the level of the ground

MA = L / h

where:

MA = mechanical advantage

L = Length of the inclined plane = 10 [m]

h = elevation = 2.5 [m]

MA = 10/2.5

MA = 4

A model rocket is launched from the ground. It starts from rest and accelerates upward at 15.0 m/s2 for 3.00 s. Disregard gravity. What is the V2? b. Then, it has a downward acceleration of -10.0 m/s2 until it reaches its highest point. What is the highest above the ground that the rocket gets? c. What is the TOTAL time in the air?

Answers

Answer:

The final velocity v₂ is 45 m/s

The highest point reached by the rocket is 101.25 m

The total time spent in air by the rocket is 7.5 s

Explanation:

Given;

initial velocity of the rocket, v₁ = 0

final velocity of the rocket, v₂ = ?

upward acceleration of the rocket, a = 15 m/s²

time of acceleration, t = 3 s

The final velocity is given by;

v₂ = v₁ + at

v₂ = 0 + (15 x 3)

v₂ = 45 m/s

The highest point reached by the rocket is given by;

v² = u² + 2ah

where;

u is the initial velocity of rocket when it started decelerating.

thus, u = v₂

v is the final velocity of the rocket at its highest point = 0

0 = v₂² + 2ah

0 = (45)² + (2 x -10 )h

0 = 2025 - 20h

20h = 2025

h = 2025 / 20

h = 101.25 m

Time taken for the rocket to reach its highest point is given by;

h = ut + ¹/₂at²

101.25 = 45t + ¹/₂(-10)t²

101.25 = 45t - 5t²

5t² - 45t + 101.25 = 0

t² - 9t + 20.25 = 0

t = 4.5 s

The total time spent in air by the rocket is given by;

T = upward time + downward time

T = 3 s + 4.5 s

T = 7.5 s

Knowing that 1 inch is equal to 2.54 centimeters, convert 287 cm to inches.

Answers

Answer: 112.992

Explanation: If you divide 287 by 2.54, you will get 112.992125984. I just got rid of the five numbers after 992.

1 inch = 2.54 cm

?= 287 cm let, ? be (a)

cross multiply

2.54a= 1×287

a= 287/2.54

a= 112.992126

therefore 287 cm = 112.992126 inches.
