Answer:

A comet is cruising through the solar system at a speed of 50,000 kilometers per hour for 4 hours time. What is the total distance traveled by the comet during this time?

✓ Distance = Speed * Time Distance = 50,000 * 4 Distance = 200,000 km. Hope this helps

Two cars are traveling at the same speed of 22 m/s on a curve that has a radius of 114 m. Car A has a mass of 1040 kg, and car B

natka813 [3]

Answer:

(a) 4.25 $m/s^2$

(b) 4420 N

(c) 4.25 $m/s^2$

(d) 6842.5 N

Explanation:

(a) Centripetal acceleration of car A, $a_c$ , is given as;

$a_c = \frac{v^2}{r}$

where v = velocity of car

r = radius of curve

$a_c = \frac{22^2}{114}\\ \\\\a_c = 4.25 m/s^2$

(b) Centripetal force of car A is given as:

$F_A = m_A*a_c = m_A*\frac{v^2}{r}$

$F_A = 1040 * 4.25 = \\\\\\F_A = 4420 N$

(c) Since car A and car B have the same speed, they have the same centripetal acceleration ( $a_c = 4.25 m/s^2$ )

(d) Centripetal force of car A is given as:

$F_B = m_B*a_c = m_B*\frac{v^2}{r}$

$F_A = 1610 * 4.25 = \\\\\\F_A = 6842.5N$

In one cycle, an engine burning a mixture of air and methanol absorbs 525 J and expels 415 J, what is the engine’s efficiency?

Kay [80]

Answer:

79%

Explanation:

Energy expelled / Energy absorbed = 415/525 = 0.79 = 79%
