Basically, the temperature is a result of the average kinetic energy of all the atoms comprising the solid/liquid/gas. In solid, these atoms can just vibrate in place, leaving them to only be able to conduct and radiate heat. However, as you probably know liquids and solids take the shape of their container because the bonds between atoms are loose enough to allow them to freely move around. Due to each individual atom having its own energy, and these atoms being free to move about the liquid/gas they collide with other atoms in the substance. These collisions result in a transfer of energy. Finally, lower energy atoms "sink" and higher energy atoms "rise" thus creating a "convection current".
let the tension force in the rope attached to the sledge be "T"
θ = angle of rope with the horizontal = 40 deg
X = horizontal component of tension force "T" = 100 N
horizontal component of tension force "T" is given as
X = T Cosθ
100 = T Cos40
T = 130.54 N
Y = vertical component of the tension force = ?
vertical component of the tension force is given as
Y = T Sinθ
inserting the values
Y = (130.54) Sin40
Y = 83.91 N
Meteorite meteoroid asteroid moon give brainlest please
Answer:
we know that that frequency= n/t
= 70/20
= 3.5 Hertz
Explanation:
i think that the answer
Answer: 20.73m/s
Explanation:
The question simply wants us to calculate the speed of the pitch. The speed will be calculated as:
= Distance/Time
where,
Distance = 85 meters
Time = 4.1 seconds
Speed = Distance/Time
Speed = 85/4.1
Speed = 20.73m/s
Therefore, the speed of the pitch is 20.73m/s.
