Answer :The vapor pressure of water is greater at 50°C than it is at 10°C.
Explanation: Vapor pressure is the pressure exerted by the vapors over the surface of the liquid.
Vapor pressure is directly proportional to the temperature as more is the temperature, more liquid can be converted to vapors and more vapors will exert greater vapor pressure.
As 50 ° C > 10 ° C, at 50 ° C, vapor pressure will be more as compared to 10 ° C.
Explanation:
Motion is when an object changes position over time. The object in motion is usually in front of a reference point-an object that appears to stay in one place. The rate at which an object moves is called speed. Speed depends on both time and distance. The velocity of an object is how fast it is going in one direction
How do you know if an object has changed position?
changes position requires a point of reference. An object changes position if it moves relative to a reference point. To visualize this, picture yourself competing in a 100-m dash. You begin just behind the start line
Answer:
168 Volts
Explanation:
Use Ohm's law:
(Voltage) = (Current) x (Resistance)
(Voltage) = 21 A * 8 Ohm = 168 V
Answer: When there is an increased number of sun spots, it means the surface temperature is decreased which will decrease the temperature of the Earth's surface as well
Explanation:
Answer:
Radius r = 20.34 cm
The radius that can produces such a disk is 20.34 cm
Explanation:
Area of a circle;
A = πr^2
A = area
r = radius
Making r the subject of formula;
r = √(A/π) ........1
Given;
A = 1300 cm^2
Substituting into the equation 1;
r = √(1300/π)
r = 20.34214472564 cm
r = 20.34 cm
The radius that can produces such a disk is 20.34 cm
