Answer:
Explanation:
Using apparent = mass of liquid expelled/mass of liquid remaining × temp. rise
Mass expelled: 250-248.5=1.5g
Mass remaining =248.5g
Temp. rise= 60-30= 30ºc
= 1.5/248.5×30=0.0002012
Using real= apparent + cubic expansivty
Cubic= 3 × linear expansivty
= 3×0.000006=0.000018
0.0002012+0.000018=0.0002192

<em>✔ We have : a = v/Δt </em>
The car's acceleration is therefore 6 m/s².
To turn the aircraft, the pilot uses all three flight controls. The rudder is controlled in the cockpit by foot pedals. When the pilot presses the left pedal, the rudder deflects to the left. This deflection creates more lifting force on the right-hand side of the rudder, which moves the plane's nose to the left.
Answer:
Melting
Explanation:
The process of a solid becoming a liquid is called melting. (an older term that you may see sometimes is fusion). The opposite process, a liquid becoming a solid, is called solidification. For any pure substance, the temperature at which melting occurs—known as the melting point—is a characteristic of that substance.
Wavelength times frequency = speed of light
7.5E14 x wavelength = 300,000 m/s
Wavelength in meters = 300,000 divided by 7.5E14
