Power = Work done/Time taken
So, keeping this in mind,we can solve it as follows:
= 700/3.1
= 7000/31
= 225.80 W
They are all classified in the same kingdom
Answer:
4 TIMES
Explanation:
As centripetal acceleration has formula a =v^2/r. as r is constant so a is directly proportional to square of speed so square of 2 is 4 hence 4 times
I encountered this same question, these were the choices given.
1). In the atom, the particles of the cathode rays are embedded in a diffuse cloud of positive charge.
<span>2).Cathode rays have mass. </span>
<span>3).Matter contains positive and negative charge. </span>
<span>4).The positive component of matter is also particulate in nature. </span>
<span>5).Particles of the cathode rays are fundamental to all matter. </span>
<span>6).An atom is divisible. </span>
<span>7).Particles of the cathode rays are negatively charge.
</span>
There are more than one correct statement. These statements are:
<span>2).Cathode rays have mass.
</span><span>3).Matter contains positive and negative charge.
</span>5).Particles of the cathode rays are fundamental to all matter. 6).An atom is divisible.
