Answer:

Chain reaction is possible by neutron

Explanation:

Nuclear reaction is mainly two types,

⇒ Nuclear Fission : heavy atom split into two light atom.

Ex. Uranium, thorium

⇒ Nuclear fusion : lighter atom combine together

Ex. Hydrogen to helium

In fusion reaction the large amount of energy is produced as compare to fission reaction.

Sun gets brighter by fusion reaction.

In case of uranium fission reaction is possible by colliding neutron.

Determine which heat transfers below are due to the process of conduction. I) You walk barefoot on the hot street and it burns y
Taya2010 [7]

Answer:

I) You walk barefoot on the hot street and it burns your toes.

II) When you get into a car with hot black leather in the middle of the summer and your skin starts to get burned.

Explanation:

In conduction mode of heat transfer we know that the energy is transferred from one system to other system due to direct contact of two bodies

Here due to this direct contact the energy is transferred via a given solid or liquid medium

In this type of heat transfer medium particles will remain in its own position only the energy is transferred.

So here we can say the correct answer will be

I) You walk barefoot on the hot street and it burns your toes.

II) When you get into a car with hot black leather in the middle of the summer and your skin starts to get burned.

Consider an old-fashion bicycle with a small wheel of radius 0.17 m and a large wheel of radius 0.92 m. Suppose the rider starts
Gala2k [10]

Answer:

10259.6 m

Explanation:

We are given that

Radius of small wheel,r=0.17 m

Radius of large wheel,r'=0.92 m

Initial velocity,u=0

Time,t=2.7 minutes=162 s

1 min=60 s

Velocity,v=10m/s

Time,t'=13.7 minutes=822 s

Time,t''=4.1 minutes=246 s

v=u+at

Substitute the values

10=0+162a=162a

a=\frac{10}{162}=0.0617m/s^2

s=ut+\frac{1}{2}at^2

Substitute the values

s=\frac{1}{2}(0.0617)(162)^2=809.6 m

s'=vt'=10\times 822=8220 m

a'=\frac{v}{t''}=\frac{10}{246}

s''=\frac{1}{2}a't''^2=\frac{1}{2}\times \frac{10}{246}(246)^2=1230 m

Total distance traveled by rider=s+s'+s''=809.6+8220+1230=10259.6 m

Tom is sitting facing forward in the train as it is getting ready to leave the station. He puts a smooth ball on the train floor
Vesnalui [34]

According to Newton's first law of motion, what happens to the ball is  the ball rolls backward.

<h3>What is the first law?</h3>

This means that an object at rest or in motion will remain uniformly rectilinear and tend to be in that state if the net force on it is zero.

In this case, we have to think that the ball is at rest and the train is moving with a velocity that way, the reaction of the ball will be to go in the opposite direction to the motion.

"The ________ method can determine whether a string contains a value that can be converted to a specific data type before it is
dem82 [27]

Answer:

The method to determine whether a string contains a value that can be converted to a specific data type before it is converted to that data type

Explanation:

The Java string includes () method to check whether a particular sequence of character is the part of given sub string or not.

One string contain another string in Java or not.

The indexof() to check the string and substring in java

Hence java string include () method to check  whether a string contains a value that can be converted to a specific data type before it is converted to that data type
