What is the acceleration during the pushing-off phase, in m/27 Express your answer in meters per second squared. A bush baby, an

Sindrei [870]

Answer:

$a = 12.78 g's$

Explanation:

Height reached by the object after push off is given as

$H = 2.3 m$

$v_f^2 - v_i^2 = 2 a s$

now we have

$0 - v^2 = 2(-9.81)(2.3)$

$v = 6.72 m/s$

now we know that this push last for total distance of 0.18 m

so during the push we will have

$v_f^2 - v_i^2 = 2 a d$

$6.72^2 - 0 = 2a(0.18)$

$a = 125.35 m/s^2$

now in terms of g = 9.81 m/s/s we have

$a = \frac{125.35}{9.81} gs$

$a = 12.78 g's$

How much heat in kilojoules is required to melt an ice cube with a mass of 18.6 g at 0 °C? The Lf for water is 333 J/g.

blagie [28]

Q = m.Lf.
Here, m = 18.6 g
Lf = 333 J/g

Substitute their values,
Q = 18.6 × 333 = 6193.8 J

We know, 1 KJ = 1000 J
So, 6193.8 J = 6.193 KJ

In short, Your Answer would be Option D

Hope this helps!

Pulleys and Belts. In a pulley system, pulley A is moving at 1500 rpm and has a diameter of 15 in. Three pulleys, B, C, and D, a

NeTakaya

For this question I would use the similarities between pulley A, to each pulley of the question.

<span>1. A speed of 1750 rpm is required when the drive belt is connected to pulley B. What is the diameter of pulley B?</span>

15inches / 1500rpm = (x<span>) inches / 1750rpm</span>

(x) = 15 inches * 1750 rpm / 1500rpm

(x) = 17.5 inches

2.A speed of 2000 rpm is required when the drive belt is connected to pulley C. What is the diameter of pulley C?

15inches / 1500rpm = (x) inches / 2000rpm

(x) = 15 inches * 2000 rpm / 1500rpm

(x) = 20 inches

3. A speed of 3250 rpm is required when the drive belt is connected to?

15inches / 1500rpm = (x) inches / 3250rpm

(x) = 15 inches * 3250 rpm / 1500rpm

(x) = 32.5 inches
