• The choir is a musical ensemble of singers. Choral music is music specially written for performances by such ensembles. Choirs can play music from the repertoire of classical music from the Middle Ages to the present, or from the repertoire of popular music.
• Singing in tune is often so difficult for the beginning singer that they might believe they will never be able to sing at all. Singing in tune is a developed skill and there are a few secrets to developing it quickly. I was one of those who could not sing in tune and I believed I just didn't have the singing gift.
• It's even harder in a choir as everyone who is a part of it has to sing in tune together as a whole.

• 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
