Explanation:
d= 80km = 8000m
t = 45 min = 45/60 h
= 0.75 h
V= ?
we know that,
V = d /t
or,V= 80 km / 0.75 h
- or, V= 106.67 km/hr
or,V= 106.67×1000m / 3600 s
2. or, V= 29.63 m/s
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 saturated solution is one that cannot dissolve any more of the substance that is mixed into it.
Answer: magnet, motor
Explanation :
Hans Christian Orsted was the scientist who gives the relation between electricity and magnetism. He found that the magnetic needle gets deflected on the application of electric current to the circuit.
He observed that the current carrying wire acted like a magnet.
In 1821 Michael Faraday understands Orsted's work and invented electric motor. An electric motor is a device which is used to convert electrical energy to mechanical energy.
