Break the circuit and apace a meter actually within the circuit.
Answer:
The correct option is;
3 times of X
Explanation:
The algebraic properties of a vector are;
Multiplicative identity for real numbers 1
1P = P for each P
Scalar associative property = r(sP) = (rs)P
Scalar distributive property (r + s)P = rP + sP
Vector distributive property r(P + Q) = rP + rQ
Additive inverse of a vector such that a vector P has an inverse -P such that we have;
P + (-P) = 0
Vector associative property (P + Q) + R = P + (Q + R)
Vector commutative property P + Q = Q + P.
Answer:
b. Gasloine evaporating into the air
I tryed to answer
There are many ways to solve this but I prefer to use the energy method. Calculate the potential energy using the point then from Potential Energy convert to Kinetic Energy at each points.
PE = KE
From the given points (h1 = 45, h2 = 16, h<span>3 </span>= 26)
Let’s use the formula:
v2= sqrt[2*Gravity*h1] where the gravity is equal to 9.81m/s2
v3= sqrt[2*Gravity*(h1 - h3 )] where the gravity is equal to 9.81m/s2
v4= sqrt[2*Gravity*(h1 – h2)] where the gravity is equal to 9.81m/s2
Solve for v2
v2= sqrt[2*Gravity*h1]
= √2*9.81m/s2*45m
v2= 29.71m/s
v3= sqrt[2*Gravity*(h1 - h3 )
=√2*9.81m/s2*(45-26)
=√2*9.81m/s2*19
v3=19.31m/s
v4= sqrt[2*Gravity*(h1 – h2)]
=√2*9.81m/s2*(45-16)
=√2*9.81m/s2*(29)
v4=23.85m/s
