Answer:
The distance traveled by the car is 60 miles and the displacement of the car is 20 miles in the north direction.
Explanation:
The distance is the total length of the car's path.
d = 40 mi + 20 mi
d = 60 mi
The displacement is the distance between the starting position and the final position.
x = (40 − 20) mi N
x = 20 mi N
1: Equilibrium
[] When two forces are equal in opposite directions, they are in a state of equilibrium
2: Friction
[] It can be hard to sometimes slide a paper across a table, roll a car across the ground, etc etc. This is because of a force called friction which resists motion
3: Displacement
[] Work is only "done" when the object or surroundings are having movement, or in motion, and this creates displacement
4: Force
[] A force is a push/pull in any direction, this is a simple definition so not much can be added.
5: Inertia
[] Inertia is a force that likes to remain unchanged, or without movement
6: Effort
[] "Meg is holding up weight without movement. She hasn't done any work since it did not move, but is tired. Why?" Effort! She still put in effort even though no "work" happened
7: Work
[] Force times displacement is the equation for work
8: Motion
[] Look back to #3, when there is motion we can tell work is done

Answer:
The apparent depth d = 19.8495 cm
Explanation:
The equation for apparent depth can be expressed as:
here;
= refractive index in the first liquid = 1.75
= refractive index in the second liqquid= 1.33
∴
d = 15(1.3233
) cm
d = 19.8495 cm
Answer:
hope this helps love! There are three methods of heat transfer: conduction, convection, and radiation. Cooking of food usually uses a combination of these methods. Conduction transfers the heat using direct contact; food is heated directly in a metal pan, in a liquid, or surrounded by air. ... The heat from the water is transferred to the egg.
Explanation:
When the water is heated, thermal expansion happens so the particles move farther apart and then the hot water moves up because it is less dense then the colder water. ... Convection is happening because when air is heated by the fire, the air becomes less dense and moves up because denser things sink.
Answer:
Impedance, Z = 107 ohms
Explanation:
It is given that,
Resistance, R = 100 ohms
Inductance, 
Capacitance, 
Frequency, f = 60 Hz
Voltage, V = 120 V
The impedance of the circuit is given by :
...........(1)
Where
is the capacitive reactance, 
is the inductive reactance, 
So, equation (1) becomes :
Z = 106.26 ohms
or
Z = 107 ohms
So, the impedance of the circuit is 107 ohms. Hence, this is the required solution.
