Dude what is going on here
Answer:
Explanation:
The equation is balanced because the mass and charge are equal on both sides of the reaction equation.
In a nuclear reaction, one nucleus is transformed into another. In this case of the equation shown, the radon nucleus is being transformed into a polonium nucleus with the emission of an alpha particle.
The equation is balanced because a total mass of 219 is found on both sides of the reaction equation and a total charge of 86. Recall that an alpha particle is the same as a helium nucleus with a mass of four units and a charge of two units.
Answer:
The angular velocity is the rotation speed, which is the angle of rotation
of the windmill per second, which is 2·π radians.
Explanation:
Answer:
490 Joule
Explanation:
Solution:
Given,
- Mass (m) = 5 kg
- Acceleration due to gravity= 9.8 m/s
- Height (h)= 10 m
Here,
Potential Energy (P.E.)= mgh
=5×9.8×10
= 490 Joule
