How can you get acceleration when talking about speed?

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

just copy what u wrote and paste and search in google

the strength of the electric field on the point charge= n/c

the electric field is given by

e=

q=6μc= 6 x 10⁻⁶c

r=100 m

e=

e=5.4 n/c

so the electric field on the point charge= 5.4n/c
