How can pavement markings indicate that you are driving in the right direction?
Answer:
There is a yellow line on your left and a white line on your right.
Explanation:
The yellow line between the roads separate the oncoming traffic lane, so the drivers won't get confused. Since the driver is on the right side of the road, the yellow line would be on their left, since the middle line (yellow line) is in the middle of the road.
.Block A of mass 30 kg is resting on Block B of 15 kg and both blocks are connected via a
light and inextensible cable, which runs over a light and smooth pulley. Determine the
tension, T, in the cable and the acceleration of Block B, aB, as it moves up the inclined
plane.
The tension in the cable and the net acceleration of the block B are 291.814 newtons and 0.112 meters per square second, respectively.
How to determine the tension and the acceleration of block B
Based of the representation seen in the image, an external force moves the block A downwards and the block B moves upwards and with an net acceleration of same magnitude due to the cable. By Newton's laws we construct the free body diagrams for each mass and that can be seen in the image seen below.
The motion equations are described below:
Mass A
250 N - 0.4 · Na - T + (30 kg) · (9.807 m / s²) · sin 30° = (30 kg) · a (1)
Na - (30 kg) · (9.807 m / s²) · cos 30° = 0 (2)
Mass B
- T + 0.4 · Na + 0.3 · Nb + (15 kg) · (9.807 m / s²) · sin 30° = - (15 kg) · a (3)
Nb - Na - (15 kg) · (9.807 m / s²) · cos 30° = 0 (4)
By (2):
Na = (30 kg) · (9.807 m / s²) · cos 30°
Na = 254.793 N
By (4):
Nb = 254.793 N + (15 kg) · (9.807 m / s²) · cos 30°
Nb = 382.190 N
Then, we have the following system of linear equations:
T + (30 kg) · a = 250 N - 0.4 · Na + (30 kg) · (9.807 m / s²) · sin 30°
T + 30 · a = 295.188
T - (15 kg) · a = 0.4 · Na + 0.3 · Nb + (15 kg) · (9.807 m / s²) · sin 30°
T - 15 · a = 290.127
The solution of the linear system is T = 291.814 N and a = 0.112 m / s².

if the mind drum diameter 6 m calculate how far the counterweight which is 10 tons will lift for each single rotation of the Drum Show all calculations
Measure the diameter of the drum. This is the distance across a circular end. For instance, the diameter might measure 18 inches. Divide the diameter in half.
How to find single rotation of the Drum?
The diameter of the drum is : d=6m
We understand that in a winch there's a cable that's connected from the weight to be raised to the drum, around which it's is rolled. So the distance the counterweight is lifted coordinates to the circumference of the drum. The expression to calculate the counter weight lifted in every single rotation of the drum is provided by,
h lift =C = πd
Substituting the importance of d in the above expression .
C=227×6C=18.85m
Thus, the counter weight lifted in each circuit of drum is
18.85m.

2. Two charges 160μC and -250μC are placed together at a distance of 150 centimeter apart. Find the force of attraction between each other. Also explain the nature of the force [Repulsing force = +ve, Attraction force = -ve]
The answer is -0.016 N, and as it negative, the nature of the force is attractive.
Finding the force of attraction
Coulomb's Law is given by :
[tex]\boxed {F = \frac{kq_{1}q_{2}}{r^{2}}}[/tex]
Solving
F = 9 × 10⁹ × 160 × 10⁻⁶ × -250 × 10⁻⁶ / (150 × 10⁻³)²F = -360000 × 10⁻³ / 22500 × 10⁻⁶F = -16 × 10⁻³F = -0.016 N
