Answer: A

Explanation: because The kinetic energy of a moving object is directly proportional to its mass and directly proportional to the square of its velocity. The kinetic energy of an object can be changed by doing work on the object.

What is the difference between a tropical storm and a hurricane
vazorg [7]

Answer and Explanation:

Tropical storm:

The point at which the tropical depression intensifies and can sustain a maximum wind speed in the range of 39-73 mph, it is termed as a tropical storm.

Hurricane:

A hurricane is that type of tropical cyclone which includes with it high speed winds and thunderstorms and the intensity of the sustained wind speed is 74 mph or more than this.

Hurricanes are the most intense tropical cyclones.

The only difference between the tropical storm and hurricane is in the intensity.

Willing to give out Brainliest: 3.00 m^3 of water is at 20.0°C If you raise its temperature to 60.0°C, by how much will its volu
lozanna [386]

Answer:

The answer is below

Explanation:

Charlee's law states that the volume of a gas is directly proportion to the temperature of the gas at constant pressure. That is:

V = kT, where V = volume and T = temperature, k = constant. Therefore:

V / T = k

\frac{V_1}{T_1}=\frac{V_2}{T_2}

Given that: V_1=3\ m^3, T_1=20^oC=(20 + 273)K=293\ k,T_2=60^oC=(60 + 273)K=333\ k.\\\\\frac{V_1}{T_1}=\frac{V_2}{T_2}\\\\\frac{3}{293}=\frac{V_2}{333}    \\\\V_2=\frac{3}{293}*333\\\\V_2=3.41\ m^3\\

The new volume is 3.41 m³. That is it expands by 0.41 m³

If a nichrome wire has a resistance of 15Ω and is connected across the terminals of a 3.0 V flashlight battery, how much current
scoray [572]

Answer:

0.20 A

Explanation:

The current in the wire is given by Ohm's law:

I=\frac{V}{R}

where

I is the current

V is the voltage

R is the resistance

In this problem,

V = 3.0 V is the voltage

R=15 \Omega is the resistance

Substituting into the formula,

I=\frac{3.0 V}{15 \Omega}=0.20 A

if the angular diameter of an object is 15 arc seconds and it is 1.4 billion kilometers away, how big is its physical size?
kaheart [24]

the actual diameter of the object is 1.017×10⁵km

actual diameter, d = any line segment that passes through the center of the circle

angular diameter, θ = the angle that an actual diameter of an object makes.

distance, D= the actual path travel

distance of the object ,D= 1.4 billion = 1.4×10⁹km

angular diameter of an object,θ = 15arc

                            θ  = 15 ×π/ (60×60×180) rad

                                                 [ ∵ 1 revolution = 2π = 360°×60×60]

   Using the relation,

     θ = d/D   {angular diameter = actual diameter/ distance}

     d =  θD

      d =  1.4×10⁹×[15×3.14/(60×60×180) ] km

         =  1.017×10⁵km

This shows the actual diameter of the object is  1.017×10⁵km

It is the physical size of object.
