Force is a vector quantity
so pulling from opposite side will be negative
so
750+(-500)= 250N
C is the right answer
becauseause the man on the right applies greater force.
Answer:
Hi myself Shrushtee
Explanation:
Neutral carbon-12 (or any carbon atom) has 6 electrons with a total negative charge of 6e- orbiting a nucleus with a total positive charge of 6e+, so that the total net charge is zero. The nucleus is made up of 6 protons, each with a positive charge of e+, and 6 neutrons, each with zero charge.
please mark me as brainleist
The brain takes in what your eyes see and what your ears hear. When you feel endangered and have an instinct to run, or decide you want to move at all, your brain sends signals to your body to tell your muscles to do so.
Answer:
The potential difference across the source is 30.45 V.
Explanation:
In this setup we have a voltage divider, we were given the voltage difference on one of the resistors, we know that the difference pottential from the source in this case is the sum of the voltage in each individual resistor, so we can use the following equation to solve this problem:
V_resistor5.4 = (V_source)*(R_5.4)/(R_5.4+R_8.3)
V_source = (V_resistor5.4)*(R_5.4+R_8.3)/(R_5.4)
V_source = (12)*(5.4+8.3)/5.4
V_source = (12)*(13.7)/5.4 = 30.45 V
he potential difference across the source is 30.45 V.
