Answer: The answer is A
Explanation: There is a strong relationship between them because if you get more sleep then you will have more energy and focus more on the exam.
force between two parallel wire is
f/l = mueo*i1i2/2pir
f/l = 2*10^-7*i1i2/rl
i2 = f*r/2*10^-7*i1
i2 = 342.9 A
Answer:
The answer is 8.44*10^9 Newton
Explanation:
The equation for universal gravitation is:
Where:
G= 6.674×10^−11 N · (m/kg)^2
M(earth)=5.972 × 10^24 kg
M(asteroid)=5.0×10^13 kg
r=1.537*10^9 m (Calculated from average distance between moon and earth)
The force will be:
8.44*10^9 Newton
Answer:
D. Hotel 3 because they will experience beach erosion
Explanation:
A beach groin is a man made structure which is used to protect the beach from sand erosion. It makes the water current to deviate in the other direction thus preventing the beach in the groin area to be eroded.
In the context, constructing a groin by Hotel 2 will prevent beach erosion in its area but this will lead to the soil erosion for the beach in front of hotel 3, thus affecting hotel 3. So Hotel 3 can sue Hotel 2 and stop the groin being constructed by the Hotel 2.
Hence the correct option is (D).
Answer:
a) x = 0.200 m
b)E = 3.84*10^{-4} N/C
Explanation:
DISTANCE BETWEEN BOTH POINT CHARGE = 0.5 m
by relation for electric field we have following relation
according to question E = 0
FROM FIGURE
x is the distance from left point charge where electric field is zero
solving for x we get
x = 0.200 m
b)electric field at half way mean x =0.25
E = 3.84*10^{-4} N/C
