Answer:
When you ask a question, only two people can answer. When there are two answers, a little crown should appear at the bottom right hand corner. All you have to do is click the crown and it gives Brainliest. But you can only give it to one person per question
Explanation:
Answer:
The right hand rule states that: to determine the direction of the magnetic force on a positive moving charge, ƒ, point the thumb of the right hand in the direction of v, the fingers in the direction of B, and a perpendicular to the palm points in the direction of F.
Explanation:
Answer:
3850 J
Explanation:
= initial volume of the gas = 30 L = 0.03 m³
= final volume of the gas = 65 L = 0.065 m³
= Constant pressure of the gas = 110 kPa = 110000 Pa
= Work done by the gas
Since the pressure is constant, Work done by the gas is given as

Answer:
a.The atomic radii increases from top to bottom within a group.
Explanation:
We know that
When we move from top to bottom in a group then the atomic radii increases When we move from top to bottom in a group then number of shell increases.
Therefore, the distance of electron in outermost shell from the nucleus is also increase.Hence, the atomic radii increases.
But when we move from left to right in a group then nuclear pull increases because number of electron increases in the same shell.
Therefore, size of atom decreases and atomic radii decreases.
Hence, the atomic radii increases as one moves from top to bottom within a group.
