The boiling point of sulfur is 444.6 celsius .sulfur melting point is 586.1 fahrenheit lower than its boiling?
rewona [7]

Answer:

(a) Melting point is 136.8°C

(b) Melting point is 278.24°F

Boiling point is 832.28°F

(c) Melting point is 409.8K

Boiling point is 717.6K

Explanation:

(a) 586.1°F = 5/9(586.1 - 32)°C = 307.8°C

Melting point = 444.6°C - 307.8°C = 136.8°C

(b) Melting point = 136.8°C = (9/5×136.8) + 32 = 278.24°F

Boiling point = 444.6°C = (9/5×444.6) + 32 = 832.28°F

(c) Melting point = 136.8°C = 136.8 + 273 = 409.8K

Boiling point = 444.6°C = 444.6 + 273 = 717.6K

a tire rolls from rest to an angular velocity of 6 radians per second. the angle it turns through is 12 radians. what is the ang
True [87]

Answer:

\alpha =1.5\ rad/s^2

Explanation:

Given that,

Initial angular velocity, \omega_i=0

Final angular speed, \omega_f=6\ rad/s

Angular displacement, \theta=12\ rad

We need to find the angular acceleration of the tire. We can find it using the third equation of rotational kinematics. So,

\omega_f^2-\omega_i^2=2\alpha \theta\\\\\alpha =\dfrac{\omega_f^2-\omega_i^2}{2\theta}\\\\\alpha =\dfrac{6^2-0^2}{2\times 12}\\\\\alpha =1.5\ rad/s^2

So, the angular acceleration of the tire is equal to 1.5\ rad/s^2.

Brilliant_brown [7]

Given that,

A ball is thrown upward. At a height of 10 meters above the ground, the ball has a potential energy of 50 Joules. It is moving upward with a kinetic energy of 50 Joules.

We need to find the maximum height h reached by the ball. Let at a height of 10 meters, it has a potential energy of 50 Joules. So,

mgH=50\\\\mg=\dfrac{50}{h}\\\\mg=\dfrac{50}{10}\\\\mg=5\ N ........(1)

Let at a height of h m, it reaches to a maximum height. at this point, it has a total of 100 J of energy. So,

mgh=50+50\\\\mgh=100\\\\h=\dfrac{100}{5}\\\\h=20\ m

So, the correct option is (E) "h = 20 m".
