If a spaceship weighs 2500kg and is traveling at the speed of light, how much energy does the ship have?

Answer:

distance of object from mirror=distance of image from mirror

so distance between object and image=distance of object from mirror+distance of image from mirror

=2 x distance of object from mirror

=2 x (3+0.4)m

=2 x (3.4)m

=6.8 m

Answer:

b. migration

A migration can be defined as the changes that occur in the behavior, structure, physiology of the organism so as to allow it to survive in unfavorable environmental conditions. Behavioral adaptation can be defined as the changes that occur in an organism's behavior which affects it's actions and helps it to survive like choice of mating partner, calling the mates for copulation and migration to different location all are the examples of the behavioral adaptations

Explanation: Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations. Adaptations are the result of evolution. Evolution is a change in a species over long periods of time.

To Find: Diameter of soap bubble =? Solution: By Laplace's law of spherical membrane for a bubble. (Pi– Po) = 4T / r.

Answer it will move slower:

Explanation: cause the force that’s opposite of it

Answer:

A

Explanation:

Answer:

According to Pascals law, THE PRESSURE EXERTED TO A CONFINED LIQUID IS TRANSMITTED EQUALLY AND UNDIMINISHED IN ALL DIRECTIONS THROUGHOUT THE MASS OF THE LIQUID--Blaise Pascal

so the pressure at A2 must be equal to A1

buy however the F1 will be less than F2 since:

P1=F1/A1 and P2=F2/F1

P1=P2 according to Pascal

so, F1/A1=F2/A2

with less amount of force at P1 THE force gets multiplied.

Therefore it's obvious that option A and B is wrong. I can't see option C properly.

but, you are going to have this option.

C.F1>F2

so the option with F1>F2 is correct

Concept Used :-

Here, we will use the concept of speed, distance and time

We have given two conditions here

We know that,

[tex]\bold{\pink{ Speed = }}{\bold{\pink{\dfrac{ Distance }{Time}}}}[/tex]

Subsitute the required values in the above formula :-

[tex]\sf{1.4 = }{\sf{\dfrac{ 500 }{t}}}[/tex]

[tex]\sf{ t = }{\sf{\dfrac{ 500 }{1 .4}}}[/tex]

[tex]\sf{ t = }{\sf{\dfrac{ 500 }{1.4}}}[/tex]

[tex]\bold{\boxed{\red{ t = 357.14 \:sec }}}[/tex]

Hence, Time taken by Elena to cover distance of 500 m is 357.14 sec

We know that,

[tex]\bold{\pink{ Speed = }}{\bold{\pink{\dfrac{ Distance }{Time}}}}[/tex]

[ Speed = 1.4 * 60 × 60/1000

Speed = 1.4 × 18/5 = 5.04 km/h }

Subsitute the required values in the above formula :-

[tex]\sf{ 5.04 = }{\sf{\dfrac{ S(Distance)}{2}}}[/tex]

[tex]\sf{ S = 5.04 }{\sf{\times{ 2}}}[/tex]

Based on the length of a football field and the timeline of earth's history, the first 10 yards represents 460 million years.

Beginning from 460 million years ago, there was massive explosion and expansion of life on earth.

A timeline of earth's history shows the events that occurred from the beginning when earth was formed 4.6 billion years ago until today.

In this activity, a football field is used to represent the timeline of earth's history.

Each end of the football field represents the two end zones, Earth's beginning and TODAY end zone.

Thus, the first 10 yards equals = 46,000,000 × 10 The The first 10 yards = 460,000,000 years.

From the TODAY end zone, the the first 10 yards = 460,000,000 years.

460,000,000 years ago marked the time from the appearance of the first plants until humans and all life on earth as it is today.

This, meant that within this period, there was massive explosion and expansion of life on earth.

Explanation:

The heat capacity depends is the heat absorbed by the calorimeter as

the temperature changes.

Response:

Mass of the vessel. m₁ = 200 gram

Temperature of the water, T₁  = 24°C

Mass of the warm water, m₂ = 112 grams

Temperature of the warm water, T₂ = 42°C

Resultant temperature of the water, T₃ = 30°C

The heat capacity of the water = 4.184 J·Kg⁻¹·K⁻¹

Let C represent the thermal capacity of the calorimeter

We have;

Change in heat, ΔH = m·c·ΔT

Therefore;

112 × 4.184 × (42 - 30) = 200 × 4.184 × (30 - 24) + C×(30 - 24)

5623.296 = 5020.8 + 6·C

6·C = 5623.296 - 5020.8 = 602.496

The speed of the object falling freely from rest for the given distance is 50.09m/s.

Given the data in the question:

A free fall is simply any motion of a body where gravity is the sole influence.

From the third equation of motion;

[tex]v^2 = u^2 + 2gh[/tex]

Where v is final velocity, u is initial velocity, h is height and g is acceleration due to gravity ( [tex]g = 9.8m/s^2[/tex] ).

To determine the speed of the falling object, we input our values into the expression.

[tex]v^2 = u^2 + 2gh\\\\v^2 = (0)^2 + [ 2 * 9.8m/s^2 * 128m ]\\\\v^2 = 2 * 9.8m/s^2 * 128m\\\\v^2 = 2508.8m^2/s^2\\\\v = \sqrt{2508.8m^2/s^2} \\\\v = 50.09m/s[/tex]

Therefore, the speed of the object falling freely from rest for the given distance is 50.09m/s.

Answer:

B) 4 m/s²

Explanation:

[tex] \boxed{ \sf{ F= m \times a}}[/tex]

Here,

Substituting the respective values for F and m:

==> 220 = 55 × a

==> 220 = 55 × a

dividing the equation by 55:

==> 4 = a

Therefore, an object of 55 kg when pulled across a frictionless surface by a force of 220 N accelerates at 4 (m/s)/s

The uncertainty in the position of the proton is 1.1 x 10⁻¹³ m.

The velocity of the proton is calculated as follows;

[tex]v = \frac{1}{10} \times 3\times 10^8 \ m/s = 3 \times 10^7 \ m/s[/tex]

precision of the velocity, Δv = 0.01 x 3 x 10⁷ = 3 x 10⁵ m/s

The uncertainty in the position of the proton is calculated as follows;

[tex]\Delta xm\Delta v= \frac{h}{4\pi} \\\\\Delta x = \frac{h}{4\pi m\Delta v} \\\\\Delta x = \frac{6.67 \times 10^{-34} }{4\pi \times 1.67 \times 10^{-27} \times 3\times 10^5} \\\\\Delta x = 1.1 \times 10^{-13} \ m[/tex]
