Lie flat on your back and keep your knees bent.

• The answer to the blank will be "keep".
• The sentence is giving a command or an order to someone to lie flat on the ground and to keep the knees bent.
• The form of the verb "bend" will also be changed to 'bent'.
• The opposite of bend is to straighten up.

Explanation:

this is the answer

now u can understand

• Mass of Hammer = 1 kg
• Mass of Iron Nail = 0.2 kg (200g)
• Velocity of Hammer = 50m/s

Rise (or change) in the temperature if the Hammer uses half of its energy in heating the nail

First, Let's Find out the initial energy of the Hammer:

[tex] \implies \displaystyle \rm ke = \frac{1}{2} m {v}^{2} [/tex]

[tex] \implies \displaystyle \rm ke = \frac{1}{2} {50}^{2} [/tex]

[tex] \implies \displaystyle \rm ke = \frac{1}{2} {2500}[/tex]

[tex] \implies \displaystyle \rm ke = {1250}j[/tex]

So, The initial Energy of Hammer = 1250 J

As Given, Half of the energy is used in Heating up the Iron nail,

So, Q = Initial Energy/2

or, Q = 1250/2

or, Q = 625

So, The heat energy produced is 625J

Now, using the Formula :

[tex] \implies \displaystyle \rm q = mc \triangle t[/tex]

[tex] \implies \displaystyle \rm 625= 0.2 \times 419 \times \triangle t[/tex]

[tex] \implies \displaystyle \rm 3125= 419 \times \triangle t[/tex]

[tex] \implies \displaystyle \rm\triangle t = \frac{3125}{419} [/tex]

[tex] \implies \displaystyle \rm\triangle t = 7.4[/tex]

So, the Change in Temperature = 7.4°C

Answer:

some french scientists did an experiment turn into passive voice

"Bite off more than you can chew"

Idioms:

The meaning of the idiom "Bite off more than you can chew" is to take a commitment which one cannot fulfill. Hence, in the given sentence,

Sam seems to have taken up a project that he cannot finished.

The most appropriate idiom to replace the line "taken up a project that he cannot finished", is "Bite off more than you can chew".

Answer:

10375/1000 i pray that this answer will help you

Answer:

Write 10.375 in --

[tex] \frac{10.375}{1} \\ [/tex]

Now, multiply both numerator and denominator by 10 for every number after the decimal point..

[tex] \frac{10.375 \times 1000}{1 \times 1000} = \frac{10375}{1000} \\ [/tex]

Finally reduce the fraction by cutting both of then with 125 -->

[tex] \frac{10375}{1000} = \frac{83}{8} \\ [/tex]

Therefore, 83 / 8 is the required fraction in simplest form...

Hope it helped you..

Thank you !!!
