Answer:
it is maybe A but i'm not 100% sure
Explanation:
its the only one that is mixed
A short circuit is said to have occurred when two nodes of a circuit at different voltages are abnormally connected
There is said to be a short circuit when; <u>One part of a parallel circuit has a very low resistance and almost all the current will flow through this part and very little current will flow through the other part</u>
<u />
The correct option is option B.
Reason:
A circuit has to be closed or the the current path has to be closed for
current to flow. A short circuit occurs when current in a circuit flows
through an abnormal path, such as a bridge in a connection to a load that
creates a parallel path for current flow.
Almost all the current flows through the parallel path due to the low
resistance in the connection (almost zero) and the proximity to the power
source, thereby preventing current from reaching its intended destination
Therefore, the correct option is option B.;

Answer:
B. There is a direct proportion between the mass and force listed in the table.
Explanation:
From the table, the values of force increases with increase in the value of mass.
if 5kg=25 N
Finding the contant of proportionality k;
k=25/5=5
thus M=k(F)...........where M is mass in kg and F is force in newton, then
M=5F
This show that for every value of mass, we get the value of Force if we multiply by a contant k=5
This means there is a direct proportionality relation between mass and force in the table.
Answer:
t = 2.2 s
Explanation:
Given that,
Height of the roof, h = 24.15 m
The initial velocity of the pumpkin, u = 0
We need to find the time taken for the pumpkin to hit the ground. Let the time be t. Using second equation of kinematics to find it as follows :
Here, u = 0 and a = g
So, it will take 2.22 s for the pumpkin to hit the ground.
