The comet which is violent and large scale, causing sudden and violent upheaval is known as "Cataclysmic Comet"
Hope this helps!
speed of the striking object is given as
now this speed in SI units given as
So here we can use kinematic now to find the height from where it is dropped
so here we will have
now we have
now from above equation
now we know that average height of 1 story building is 3 meter
so approx total number of stories in the building will be
<span>Letter
C has the correct illustration. Two objects with the same charge (in this case,
both are positively charged) will repel each other. </span>
Letter
A is incorrect because a positive charged object will attract a negatively
charged object.
Letter
B is incorrect because both of them are negatively charged, which means they
should be repelling each other.
Answer:
Explanation:
The wording on some of these choices is very strange; I'm not sure exactly what they are stating. First of all, A. is definitely a choice because if both the charges were opposite, they would be attracted to one another as opposed to be repelled away from one another, as they are when they are both positive. What happens is that the charges go OUT from the positive charge and INTO the negative; so as far as the field lines around both charges would change direction...no; only the direction of the field lines would change on the positive charge (which is the one on the left). In that space where D is filled in by the field lines going OUT of the positive charge and INTO the negative one, the lines there are naturally closer together, and that is the point where the charge is the greatest. So if that is what is meant by the field lines getting closer together, then yes, they do. As far as choice D. again the field lines on the negative charge don't change, only the ones on the positive charge change.
