Explanation:
An acid is a substance or compound that releases hydrogen ions (H+) when in solution. In a strong acid, such as hydrochloric acid (HCl), all hydrogen ions (H+), and chloride ions (Cl-) dissociate (separate) when placed in water and these ions are no longer held together by ionic bonding.
It is the mathematical and conceptual framework for contemporary Elementary practical physicas. if that make sense to you.
Answer:84.405m,
Explanation:
Given
Person walk 42 miles due to north so its position vector is
Now he deviates to east and walk 65 miles
so its new position vector
So magnitude of acceleration is
for direction
Answer:
87000 J ;
200 J
Explanation:
Workdone = mgh
Weight = mg = 290kN = 290 * 1000=290000 N
h = distance = 30 cm = 0.3 m
Workdone = 290000 * 0.3
Workdone = 87000 J
B.)
Workdone = Force * distance
Force = 4000 N
Distance, d = 5 cm = 0.05 m
Workdone by the woman, W = 4000N * 0.05m
W = 200Nm = 200 J
Answer:
377 m
Explanation:
number of turns, N = 65
θ = 36°
B1 = 200 micro Tesla
B2 = 600 micro tesla
t = 0.4 s
induced emf, e = 80 mV
Let a be the side of the square coil.
a = 1.45 m
Total length of the wire, L = N x 4a = 65 x 4 x 1.45 = 377 m
Thus, the length of the wire is 377 m.
