Answer:
The magnitude and direction of electric field midway between these two charges is 
along AB.
Explanation:
Given that,
First charge 
second charge 
Distance = 20 cm
We need to calculate the electric field
For first charge,
Using formula of electric field
Put the valueinto the formula
Direction of electric field along AB
We need to calculate the electric field
For second charge,
Using formula of electric field
Put the valueinto the formula
Direction of electric field along AO
We need to calculate the net electric field at midpoint
Direction of net electric field along AB
Hence, The magnitude and direction of electric field midway between these two charges is along AB.
Total Current = 2 Amps
Req total = 60 ohms
Current on EF mesh = 1/3 Amp
Current on 24 ohms resistor = 1/6 Amp
Voltage on the 40ohms resistor is lefting.
Answer:
-1.03 m/s²
Explanation:
Acceleration: This can be defined as the rate of change of velocity. The S. I unit of acceleration is m/s².
Mathematically, acceleration is expressed as
a = (v-u)/t ........................ Equation 1
Where a = acceleration, v = final velocity, u = initial velocity, t = time.
Given: u = 13.60 m/s, v = 7.20 m/s t = 6.2 s.
Substituting into equation 2
a = (7.20-13.60)/6.2
a = -6.4/6.2
a = -1.03 m/s²
Note: a is negative because, the hockey puck is decelerating.
Hence the average acceleration = -1.03 m/s²
