Answer:
7200N
Explanation:
Centripetal force is directly proportional to the product of the mass and the square of the velocity and inversely proportional to the radius given.
Answer:
By the principle of corona discharge.
Explanation:
The charge on each ball will decreases over time due to the electrical discharge in air.
According to the principle of corona discharge, when the curvature is small, the discharge of the charge takes placed form the pointed ends.
Answer:
in endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products! Endothermic reactions are accompanied by a decrease in temperature of the reaction mixture.
Answer:
It will take 6.1seconds for the projectile to hit the ground.
Explanation:
In projectile, the time taken by an object to spend in air is its time if flight.
Time of flight = 2Usin(theta)/g
where u is the initial velocity = 75m/s, theta = 24°, g = 10m/s²
Time of flight = 2(75)sin24°/10
Time of flight = 150sin24°/10
Time of fight = 6.1seconds.
This means that it will take 6.1seconds for the projectile to hit the ground.
<span>Answer: b. air pressure
</span>The weather station model purpose is giving information about the weather. The information including the temperature, the air pressure, the direction of the wind and other things. The air pressure will be detected using a barometer.
The weather station doesn't give altitude/latitude or air mass.
