A ball is moving at a speed of 6.70 m/s. If the kinetic energy of the ball is 3.10 J, what is the mass of the ball?

Answers

Answer:

0.14 kg

Explanation:

The mass of the ball can be found by using the formula

[tex]m = \frac{2k}{ {v}^{2} } \\ [/tex]

v is the velocity

k is the kinetic energy

From the question we have

[tex]m = \frac{2(3.10)}{ {6.70}^{2} } = \frac{6.20}{44.89} \\ = 0.138115...[/tex]

We have the final answer as

0.14 kg

ΔH rxn = 434.7 kJ

Further explanation

Given

C+O₂⇒CO₂ ΔH=-393.5 (reaction 1)

2CO+O₂⇒2CO₂ ΔH=-566 (reaction 2)

2H₂O⇒2H₂+O₂ ΔH=483.6 (reaction 3)

Required

ΔH rxn

Solution

Reaction 1 : no change

C+O₂⇒CO₂ ΔH=-393.5

Reaction 2 : the reaction is reversed and divided by 2

CO₂⇒ CO+1/2O₂ ΔH=-283

Reaction 3 : divided by 2

H₂O⇒H₂+1/2O₂ ΔH=241.8

-------------------------------------------

C+H₂O⇒CO + H₂ ΔH rxn= -434.7 kJ

Explain why the temperature of distilled water is kept at 37°C ?

Answers

At 37°C, the pH of distilled water is actually around 6.8, which means the human extracellular fluid is quite alkaline. However, the intracellular pH of the warm-blooded human is still around 6.8. This has been confirmed by various destructive and non-destructive measurements.
(I’m sorry if I responded too late! I hope it helps)

Answer:

the temperature of distilled water is kept at 37 because it needs to kill off some microbes.

A D N A template that consists of nine nucleotides is shown. Five nucleotides have already been added to the complementary strand that is growing from left to right along the template. The left end of the growing strand is labeled 5 prime, and the right end is labeled 3 prime. The left end of the template strand is labeled 3 prime, and the right end is labeled 5 prime. An incoming d T T P has three phosphate groups. Arrows indicate that the two outermost phosphate groups split off as the d T M P with the remaining phosphate group is about to join to the 3 prime end of the growing strand.Figure 1. Model showing details of adding a deoxythymidine monophosphate (dTMP) nucleotide to a growing strand of DNAThe features of this model provide evidence for which explanation of why all growing strands are synthesized in a 5 to 3 direction?A. The two strands need to be antiparallel to bond properly.B. Thymine and adenine would not bond properly if the strand grew from 3 to 5.C. The translation of mRNA occurs in the 5 to 3 direction; therefore, the growing DNA strand must also grow in the 5 to 3 direction.D. The phosphate group, attached to the 5 carbon of the dTMP, forms a covalent bond with the oxygen atom attached to the 3 carbon of the growing strand.
