Ball A has a mass of 50 kg. Ball B has a mass of 75 kg. Both move at the same velocity. Which has a greater momentum?
Answer:
Ball B
Explanation:
I say this because its the heavier one?
The momentum of a body increases with increase in mass. Hence, among the two balls, the ball with the greater mass that is ball B has the greater momentum.
What is momentum ?Momentum is the ability of a moving object to bring the force effective to make maximum displacement. It is the product of mass and velocity.
P = mv
Thus, as the velocity and mass increases, the momentum increases. The force applied on a body with greater mass makes greater acceleration and greater momentum.
Therefore, at constant velocity, the object with the greater mass will have the greater momentum. Then, the ball with 75 kg mass is having the greater momentum.

Several electric field line patterns are shown in the diagram below. Which
of these patterns are incorrect? Select all that apply.*
Diagram A
Diagram B
Diagram C
Diagram D
Diagram E
Answer: C, E, and D is incorrect
Explanation:
C is wrong because the arrows are going inside but they should be negative not positive. E is wrong because it should be positive not negative since the arrows are going outward. D is wrong because there are more arrows in the right side instead it is suppose to be on all sideS

Suppose that the ultrasound source placed on the mother's abdomen produces sound at a frequency 2 MHz (a megahertz is 10^610 6 Hz). Sound travels through tissue at roughly the same speed as in water (v\approx 1500v≈1500m/s). Find the maximum change in frequency between the sound that is emitted by the device and the sound that is observed at the wall of the baby's heart. Treat the heart wall as a moving observer. Hint: you will need to use your answer from part (a). Give your answer as a positive number in Hz.
Answer:
the maximum frequency observed is 2.0044 10⁶ Hz
Explanation:
This is a Doppler effect exercise. Where the emitter is still and the receiver is mobile, therefore the expression that describes the process is
f ’= [tex]f_o \ ( \frac{v \pm v_o}{v} )[/tex]
the + sign is used when the observer approaches the source
typical speeds of a baby's heart stop are around 200 m / min
let's reduce to SI units
v₀ = 200 m / min (1 min / 60 s) = 3.33 m / s
let's calculate
f ’= 2 10⁶ ([tex]\frac{1500 \ \pm 3.33}{1500}[/tex])
f ’= 2.0044 10⁶ Hz
f ’= 1,9956 10⁶ Hz
therefore the maximum frequency observed is 2.0044 10⁶ Hz
in each of the following divide the second number by the first number and find the quotient:3/4,-3/8
Answer:
[tex]\dfrac{-1}{2}[/tex]
Explanation:
We need to divide the second number by the first number and the numbers are 3/4,-3/8.
First number = 3/4
Second number = -3/8
Dividing the second number by the first number.
So,
[tex]\dfrac{\dfrac{-3}{8}}{\dfrac{3}{4}}[/tex]
We know that,
[tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]
So,
[tex]\dfrac{\dfrac{-3}{8}}{\dfrac{3}{4}}=\dfrac{-3}{8}\times \dfrac{4}{3}\\\\=\dfrac{-1}{2}[/tex]
So, the answer is (-1/2)

⇒Work done=Change in kinetic energy
⇒KE=1/2mv²
⇒Mass->15000kg
⇒Velocity->72km/h
⇒KE=1/2×15000×(72)²
⇒KE=1/2×15000×5184
⇒KE=7500×5184
⇒KE=3888×10×10³J

A bobsled is on an inclined sheet of ice that is frictionless. What must be the angle of the incline if the acceleration of the bobsled is 2.77m/s^2?
Answer:
θ = 73.6º
Explanation:
To solve this exercise, let's use Newton's second law. Let's set a reference system where the x-axis is parallel to the inclined plane
with trigonometry we can find the components of the weight
sin θ = Wₓ / W
cos θ= W_y / W
Wₓ = W sin θ
W_ = W cos θ
Y axis
N - W_y = 0
N = W_y
X axis
Wₓ - fr = m a
mg cos θ - fr = m a
indicate that friction is zero, fr = 0
cos θ = a / g
θ = cos⁻¹ [tex]\frac{a}{g}[/tex]
let's calculate
θ = cos⁻¹ [tex]\frac{2.77}{9.8}[/tex]
θ = 73.6º

When a charge moves between
two points that have a potential
difference of +12.0 V, its electric
potential energy increases by
0.418 J. What is the amount
of the charge?
Include the correct sign, + or -
(Unit = C)
Answer:
+ 0.07 C
Explanation:
From the question given above, the following data were obtained:
Potential difference (V) = 12 V
Energy (E) = 0.418 J
Charge (Q) =?
The energy (E) , potential difference (V) and charge (Q) are related by the following equation:
E = ½QV
With the above formula, we can obtain the charge as follow:
Potential difference (V) = 12 V
Energy (E) = 0.418 J
Charge (Q) =?
E = ½QV
0.418 = ½ × Q × 12
0.418 = Q × 6
Divide both side by 6
Q = 0.418 / 6
Q = + 0.07 C

A car is traveling at 120 kilometers per hour with 35,000 joules of kinetic energy on the freeway when it suddenly applies its brakes and comes to a screeching stop. How much of the original 35,000 joules of energy is left?
Answer:
0 J is left (No amount of the original 35000 J energy is left)
Explanation:
From the question
Kinetic Energy (K.E) = 1/2mv²................... Equation 1
Where m = mass of the car, v = velocity of the car.
make m the subject of the equation.
m = 2K.E/v²..................... Equation 2
Given: K.E = 35000 Joules, v = 120 km/h = (120×3600/1000) = 432 m/s
Substitute these values into equation 2
m = (2×35000)/432²
m = 0.375 kg.
If a brake is suddenly apply,
Then, the velocity of the car = 0 m/s.
Therefore,
K.E = 1/2(0.375×0²)
K.E = 0 J.
From the baove analysis, No amount of the original 35000 J energy is left.

Objects 1 and 2 attract each other with a electrostatic force
of 36.0 units. If the distance separating Objects 1 and 2 is
changed to one-half the original value (i.e., halved), then the
new electrostatic force will be units.
Answer:
F = 144 units
Explanation:
For this exercise we use coulomb's law, for the initial conditions
F₀ = [tex]k \frac{q_1q_2}{r_o^2}[/tex]
indicate that the force F₀ = 36.0 units and the distance is reduced to r = r₀/2 which is the new force
F = [tex]k \frac{ q_1q_2 }{(r_o/2)^2}[/tex]
we substitute
F = 4 [tex]k \frac{q_1q_2}{r_o^2}[/tex]
F = 4 F₀
we calculate
F = 4 36
F = 144 units

Answer:
8.70 s
Explanation:
Given (in the y direction):
v₀ = 2.38 m/s
v = 0 m/s
a = 0.310 sin (-62.0°) m/s²
Find: t
v = at + v₀
0 m/s = (0.310 sin (-62.0°) m/s²) t + (2.38 m/s)
t = 8.70 s
