If a car travels 10 km north and then 10 km west, what is the MAGNITUDE of
displacement?
Answer:
The magnitude of the displacement is [tex]H = 14.14 \ km[/tex]
Explanation:
From the question we are told that
The distance of the car to north is d = 10 km
The distance of car to the west is w = - 10 \ km
The negative sign is because the direction is west
Generally applying Pythagoras theorem , the displacement is
[tex]H = \sqrt{d^2 + w^2}[/tex]
=> [tex]H = \sqrt{(10)^2 + (-10)^2}[/tex]
=> [tex]H = 14.14 \ km[/tex]

A ninja applies a force of 1250-N to a piece of 4-inch solid oak with his fist. What is the size of
the force applied to the fist by the piece of oak?
Answer:
The force is 1250-N
Explanation:
Generally according to Newtons third law , which states that for every action there is an equal and opposite reaction
Now considering the question, the action here is the force applied by the ninja while the reaction is the force applied by the oak and from Newton law both of these action are equal but opposite to each other.
Hence the force applied by the the piece of oak on the fist is 1250 N

A marble accelerates from rest at a constant rate .it travels 36 m in 12.0 sec what’s is it’s final velocity and what was the acceleration
Answer:
a = 0.50 m/s²
v = 6.0 m/s
Explanation:
Step 1: Given data
Initial velocity (u): 0 m/s (rest)Displacement of the marble (s): 36 mTime elapsed (t): 12.0 sFinal velocity (v): ?Acceleration (a): ?Step 2: Calculate the acceleration
We will use the following suvat equation.
s = u × t + 1/2 × a × t²
s = 0 × 12.0 s + 1/2 × a × (12.0 s)²
36 m = a × 72.0 s²
a = 0.50 m/s²
Step 3: Calculate the final velocity
We will use the following suvat equation.
v = u + a × t
v = 0 + 0.50 m/s² × 12.0 s
v = 6.0 m/s

4. Vector A is 7.00 units in length and points along the positive x-axis. Vector B is 5.00 units in length and points along the negative x-axis. find the magnitude and direction of A+2B 1 point
Answer:
Since the two vectors form a right angle, no components need to be found for the resultant vector - we already have them!
Vector R's x-component = 3.00 units
Vector R's y-component = 4.00 units
To solve for the magnitude of the displacement, use the distance formula: Square Root of [(3)^2 + (4)^2], which equals 5 units.
To solve for the direction of the displacement, plug in -4 (remember where it was pointing) for y and 3 for x. Tan-1(-4/3) = -53.13°, or 53.13° south of east.Please Mark as Brilliant
The magnitude of vector C is |C| = 3 and It is directed along the negative x - axis.
What is vector quantity?
A vector quantity is a quantity with both magnitude and direction.
Given is vector A is 7.00 units in length and points along the positive x-axis. and vector B is 5.00 units in length and points along the negative x-axis.
Vector A = 7 a[x]
Vector B = - 5 a[x]
Therefore, the given expression to be evaluated is -
C = A + 2B
C = 7 a[x] + 2(- 5 a[x])
C = 7 a[x] - 10 a[x]
C = - 3 a[x]
So, the magnitude of vector C is -
|C| = 3
It is directed along the negative x - axis.
Therefore, the magnitude of vector C is |C| = 3 and It is directed along the negative x - axis.

Which of the following scenarios is possible for the resultant velocity of an airplane in a strong wind to be 150 m/s?
A. The wind is blowing at 10 m/s. The airplane is flying against the wind at 140 m/s.
B. The wind is blowing at 20 m/s. The airplane is flying with the wind at 130 m/s.
C. The wind is blowing at 200 m/s. The airplane is flying with the wind at 50 m/s.
D. The wind is blowing at 50 m/s. The airplane is flying against the wind at 100 m/s.
Answer:
B. The wind is blowing at 20 m/s. The airplane is flying with the wind at 130 m/s.
Explanation:
From Physics we get that resultant velocity of an airplane is the sum of an absolute velocity and a relative velocity, that is:
[tex]\vec v_{A} = \vec v_{W}+\vec v_{A/W}[/tex] (Eq. 1)
Where:
[tex]\vec v_{W}[/tex] - Wind velocity, measured in meters per second.
[tex]\vec v_{A/W}[/tex] - Airplance velocity relative to wind, measured in meters per second.
[tex]\vec v_{A}[/tex] - Airplane velocity, measured in meters per second.
If we assume that [tex]\vec v_{W} = 20\,\hat{i}\,\,\,\left[\frac{m}{s} \right][/tex] (The airplane flies with the wind), [tex]\vec v_{A/W} = 130\,\hat{i}\,\,\,\left[\frac{m}{s} \right][/tex], then the resultant velocity of the airplane is:
[tex]\vec v_{A} = 20\,\hat{i}+130\,\hat{i}\,\,\,\left[\frac{m}{s} \right][/tex]
[tex]\vec v_{A} = 150\,\hat{i}\,\,\,\left[\frac{m}{s} \right][/tex]
Therefore, correct answer is B.
Answer:
B. The wind is blowing at 20 m/s. The airplane is flying with the wind at 130 m/s.

An oil drop (m = 1.6 x 10-16 kg) is suspended between plates separated by 1.8 cm. The voltage
across the plates is 125 V. Is this possible?
Answer:
E = V / d 125 V / .018 m = 6940 V/m electric field
F = E Q force on Q due to E
F = E n e where n is the number of electrons in Q
m g = E n e
n = m g / E e where n is the number of electrons e needed to support drop
n = 1.6 * 10E-16 * 9.8 / (6940 * 1.6 * 10E-19)
n = 1.41
Since n needs to be an integral number of charges, the drop would
not be suspended (motionless under these conditions).
When you are standing in a subway train and the train suddenly stops but your body continues to move forward. Which one of Newton's laws is this?
1st law
2nd law
3rd law
4th law
Answer:
A. 1st law.
Explanation:
Newton's first law of motion states that, an object or body will continue to be at rest or experience a uniform motion in a straight line at constant speed provided there's no action of an external force. Thus, unless compelled to change its state by an external force, a body will continue to be at rest or experience a uniform motion in a straight line.
The Newton's first law of motion is also known as the law of inertia; which is the tendency of a body to be at rest unless acted upon by an external force.
In this scenario, you are standing in a subway train and the train suddenly stops but your body continues to move forward. This is in accordance with Newton's first law of motion.
Hence, the sudden stoppage of the train generates a force which acts on the body thereby causing the passenger to tip or move forward.

A cyclist and his bicycle have a combined mass of 88 kg and
a combined weight of 862.4 N. The cyclist accelerates at 1.2
m/s2. After 2 seconds he reaches a speed of 2.4 m/s. What is
his momentum at this point?
A. 359.3 kg.m/s
B. 105.6 kg.m/s
C. 211.2 kg-m/s
O D. 36.7 kg-m/s
The momentum of the cyclist and bicycle at this point is 211.2 kg·m/s, calculated by multiplying their combined mass (88 kg) by their velocity (2.4 m/s). The correct answer is C.
The momentum of an object is defined as the product of its mass and velocity. To find the momentum of the cyclist at this point, we can use the equation: momentum = mass × velocityFirst, let's find the mass of the cyclist and his bicycle. We are given that their combined mass is 88 kg. Next, we need to find the velocity of the cyclist. We are given that he reaches a speed of 2.4 m/s after 2 seconds, and that he accelerates at a rate of 1.2 m/s². We can use the equation of motion: velocity = initial velocity + acceleration × timeThe initial velocity is 0 m/s (since the cyclist starts from rest), the acceleration is 1.2 m/s², and the time is 2 seconds. Substituting these values into the equation, we get:For more questions on momentum
