. The earth revolves around the sun in the counterclockwise direction, completing one full revolution about every 365 days. In r

LuckyWell [14K]

Answer:

Explanation:

The earth makes in 365 day 1 revolution

The earth makes in 1 day 1 / 365 revolutions

1 / 365 revolution per day

n = 1 / 365 per day .

n is called frequency of revolutions .

Angular velocity = 2π n

= 2 π x 1 / 365

= .0172 radian / day

An ice chest at a beach party contains 12 cans of soda at 4.05 °C. Each can of soda has a mass of 0.35 kg and a specific heat ca

BARSIC [14]

Below is the solution:

Heat soda=heat melon
m1*cp1*(t-t1)=m2*cp2*(t2-t); cp2=cpwater 
12*0.35*3800*(t-5)=6.5*4200*(27-t) 
15960(t-5)=27300(27-t) 
15960t-136500=737100-27300t 
43260t=873600 
t=873600/43260 
t=20.19 deg celcius

kolbaska11 [484]

Answer:

The maximum velocity is 0.489 m/s

Explanation:

Maximum velocity (v) = angular velocity (w) × radius (r)

w = 33.33 rpm = 33.33×0.1047 = 3.4897 rad/s

r = 14 cm = 14/100 = 0.14 m

v = 3.4897×0.14 = 0.489 m/s

A typical ten-pound car wheel has a moment of inertia of about 0.35kg⋅m2. The wheel rotates about the axle at a constant angular

QveST [7]

Answer:

The rotational kinetic energy of the rotating wheel is 529.09 J

Explanation:

Given;

moment of inertia I = 0.35kg⋅m²

number of revolutions = 35.0

time of revolution, t = 4.00 s

Angular speed (in revolution per second), ω = 35/4 = 8.75 rev/s

Angular speed (in radian per second), ω = 8.75 rev/s x 2π = 54.985 rad/s

Rotational kinetic energy, K = ¹/₂Iω²

Rotational kinetic energy, K = ¹/₂ x 0.35 x (54.985)²

Rotational kinetic energy, K = 529.09 J

Therefore, the rotational kinetic energy of the rotating wheel is 529.09 J
