There would be more - charges on the peanuts because they gain electrons which are represented with the - sign. There would also be more + on the cat to show that the cat’s fur is positively charged. The peanuts would be attracted to the cat because opposite charges attract.
As for explaining the first model, there should be the same amount of + and - charges on the peanuts as well as the cat to show that it is balanced and the peanuts are not attracted or repelled by the cat.
Answer:
The electric field is
Explanation:
From the question we are told that
The radius of the inner sphere is
The radius of the outer sphere is
The charge on the inner sphere is
The charge on the outer sphere is
The position from the origin is
Generally the electric field is mathematically represented as
The reason for using for the calculation is due to the fact that the position considered is greater than the but less than
Here k is the Coulomb constant with value
So
He should choose the room that’s 15 F.
-5 C = 23 F
Meaning that 15 F is below -5 C and 25 F is not.
Answer
The type of boundary formed when lithospheric plates collide is called Convergent boundary
Explanation
When plates of the lithosphere collide, they form a sub-duction zone where the denser plate will be subdued underneath the less dense one. The one subdued later melts and get destroyed. This boundary occurs when; ocean crust meets ocean crust, when oceanic and continental crust meet and where continental crust meets continental crust.
Answer:
a) Fg = m* g
b) Fg = 58.86 N
c) pointing down (towards the center of the Earth)
d) N = 58.86 N
e) pointing up
Explanation:
a) Force is defined as mass of the object times the acceleration it is subjected to. In our case, the block is subjected to the acceleration of gravity (g), therefore the force due to gravity (Fg) is Fg=m*g
b) perform the indicated product of part a):
Fg = m*g = 6 kg * 9.81 m/s^2 = 58.86 N
c) since the object is not moving, that means that the contact force exerted by the surface were the block is resting, must equal the acting force of gravity, but pointing in opposite direction, so the NET force on the block is zero. Therefore, the magnitude of the normal force (N) must equal the magnitude of the object's weight: N = 58.86 N
d) As explained in part c), the normal force must be acting in opposite direction to the force of gravity, which means pointing up.
