Answer:

A decrease in the radius and an increase in the tangential speed

Explanation:

As we know that in circular motion the acceleration towards the center of the circular path is given by the formula

a_c = \frac{v^2}{R}

now we can say that in order to increase the acceleration of the circular motion we can change the value of speed v and radius R both

here we know that

v = tangential speed

R = radius of path

so here since speed is directly dependent on the acceleration while radius is inversely depends on the acceleration so correct answer must be

A decrease in the radius and an increase in the tangential speed

If your body has a density of 955 kg/m3, what fraction of you will be submerged when floating gently in:
wel

Answer: (a) 99.5℅ submerged

(B) 96.9℅ submerged

Explanation:

For 995 kilograms per cubic meter, It'll be the 995Kg/m3 density given, divided by the density of fresh water, which is one times ten to the three kilograms per cubic meter, and this works out to 99.5 percent submerged.

If the same person with the same density was floating in salt water, salt water has a slightly higher density of 1027 kilograms per cubic meter, this works out to 96.9 percent submerged.

It takes Harry 34 s to walk from x1 = -11 m to x2 = -54 m .
miss Akunina [59]
Missing question:
"<span>What is his velocity? Please answer using two sig figs in m/s."

Solution
The relationship between velocity (v), space (S) and time (t) is
</span>v= \frac{S}{t}
<span>The space covered by Harry is
</span>S=x_1 - x_2 = -11 m-(-54 m)=43 m
<span>and so the velocity is 
</span>v= \frac{43 m}{34 s} =1.26 m/s<span>
</span>

a hot piece of copper is placed in an insulated cup. what is the final temperature of the water and copper?
slavikrds [6]

Answer:

Option C. 30°C.

Explanation:

The following data were obtained from the question:

Mass of water (Mw) = 0.5 Kg

Specific heat capacity of water (Cw) = 4.18 KJ/Kg°C

Initial temperature of water (Tw1) =

22°C

Change in temperature (ΔT) = T2 – Tw1 = T2 – 22°C

Mass of copper (Mc) = 0.5 Kg

Specific heat capacity of copper (Cc) = 0.386 KJ/kg°C

Initial temperature of copper (Tc1) = 115°C

Change in temperature (ΔT) = T2 – Tc1 = T2 – 115°C

Final temperature (T2) =..?

Note: Both the water and the piece copper will have the same final temperature and the heat will be zero since the water will cool the piece of copper.

Thus, we can determine the final temperature of the water and copper as follow:

Q = MwCwΔT + McCcΔT

0 = 0.5 x 4.18 x (T2 – 22) + 0.5 x 0.386 x (T2 – 115)

0 = 2.09 (T2 – 22) + 0.193 (T2 – 115)

0 = 2.09T2 – 45.98 + 0.193T2 – 22.195

Collect like terms

2.09T2 + 0.193T2 = 45.98 + 22.195

2.283T2 = 68.175

Divide both side by the coefficient of T2 i.e 2.283

T2 = 68.175/2.283

T2 = 29.8 ≈ 30°C

Therefore, the final temperature of water and copper is 30°C.
