Answer: 12,600,000Cm
Explanation:
From the data's;
Charges(q) = 1.8 PC equal to 1.8 x 10^¹²C
Distance = 7 micrometer, is equal to 0.0000070m
From the equation of electric dipole moment, p= q x d, where q= charge, d=distance and p is the dipole moment.
Then we have 1.8x10^¹² x 0.0000070= 12,600,000Cm
NB: The charges are identical.
The constants could be the day because the experiment is all on the same day or the person throwing the pumpkin because it will always be the same perosn
Answer:
Explanation:
dU= dq+w
dU is change in internal energy of the system
dq is the amount heat added or released by the system which be positive or negative respectivelý
And w is the amount of work done by the system or on the system which will be positive or negative respectively.
Hence,
dU= 250+80= 330 J
The change will be positive
Sorry but you tell me not to ask for help or answers but you want them yourself
To answer this question, we would need the formula for the kinetic energy which is Kinetic Energy = ½ x m x v^2
Where the following means: m is the mass of the object and v is the velocity
So At 7 m/s: Kinetic Energy = ½ x 5 x 7^2 = 122.5 J is the answer
