Answer:
A dribble ends when the player touches the ball with both hands simultaneously or permits the ball to come to rest in one or both hands. The ball being touched with both hands simultaneously (dribble with both hands) is a double dribble
Nothing in the rulebook that says a player cannot start a dribble with two hands. A dribble can end when touching both hands simultaneously, but a single dribble is OK as long as you catch the ball

This question is incomplete, the complete question is;
An automobile tire is filled to a gauge pressure of 200 kPa when its temperature is 20°C (Gauge pressure is the difference between the actual pressure and atmospheric pressure.)
After the car has been driven at high speeds, the tire temperature increases to 55°C
(a) Assuming that the volume of the tire does not change and that air behaves as an ideal gas, find the gauge pressure of the air in the tire. (kPa)
(b) Calculate the gauge pressure if the tire expands so the volume of the enclosed air increases by 10 percent. (kPa)
Answer:
a) the gauge pressure of the air in the tire is 236 kPa
b) the gauge pressure if the tire expands so the volume of the enclosed air increases by 10 percent is 205.33 kPa
Explanation:
Given the data in the question;
Gauge pressure at 20°C = 200 kPa
Absolute pressure at 20°C is; p = 200 + 101.3 = 301.3 kPa
Initial temperature T = 20°C = 20 + 273 = 293 k
Final temperature T" = 55°C = 55 + 273 = 328 K
Now, at constant volume, P"/P = T"/T
P"T = PT"
P" = PT" / T
P" = PT" / T
we substitute
P" = ( 301.3 × 328 ) / 293
P" = 98826.4 / 293
P" = 337.29
so Gauge pressure at 55°C is;
⇒ P" - 101.3
⇒ 337.29 - 101.3 = 235.99 ≈ 236 kPa
Therefore, the gauge pressure of the air in the tire is 236 kPa
b)
Final Volume V'' = V + 10% of V
V" = V + 0.1V
V" = 1.1V
we know that;
P"V"/T" = PV/T
P" = P (T"/T)(V/V")
we substitute
P" = 301.3 (328 /293 )(V/1.1×V)
P" = × 1/1.1 × V/V
P" = 337.29 × 1/1.1
P" = 306.628 kPa
so, absolute pressure at 55°C = 306.628 - 101.3 = 205.33 kPa
Therefore, the gauge pressure if the tire expands so the volume of the enclosed air increases by 10 percent is 205.33 kPa

Answers
Answer:
θ = 3.19 arc second
Explanation:
The resolution of a telescope is given by the rayleigh criterion, which establishes that two objects are separated if the principal maximum of diffraction of one of them coincides with the first minimum of diffraction of the second object, based on this the solution is given by the first diffraction minimum, the a slit is
a sin θ = m λ
with m = 1
in the case of circular apertures the equation must be found in polar coordinates, therefore a numerical constant is introduced
a sin θ = 1.22 λ
Angles are measured in radians and in these experiments they are small
sin θ = θ
θ= 1.22 λ / a
in this case a = 6.09 in, the wavelength is wrong = 550 10⁻⁹ m which is the maximum resolution of the human eye
l
et's reduce the magnitudes to the SI system
d = 6.09‘ 2.54 10⁻-2 m / 1 inch = 15.4686 10-2 m
let's calculate
θ = 1.22 550 10-9 / 15.468 10-2
θ = 15.5 10⁻⁶ rad
rad = 2.06 105 s
θ = 15.5 10⁻⁶ rad 2.06 105s/ 1 rad
θ = 3.19 s

An equipotential surface that surrounds a point charge q has a potential of 536 V and an area of 1.20 m2. Determine q.
Answers
Answer:
q = 1.84×10^-8coulombs
Explanation:
Surface area = 4πr²
r is the distance
1.2 = 4(3.14)r²
1.2 = 12.56r²
r² = 1.2/12.56
r² = 0.0956
r = √0.0956
r = 0.309m
Get the charge C
V = kq/r
536 = 9.0×10^9q/0.309
536×0.309 = 9×10^9q
165.73 = 9×10^9q.
q = 165.73/9×10^9
q = 1.84×10^-8coulombs

options: up, down, no force, north, south, east, west
Answers
Answer:
Follows are the solution to this question:
Explanation:
The magnetic force is parallel to a [tex]\bar{V} \times \bar{B}[/tex] axis, through right law. The direction would be in a reverse way for a positive particle. The gravitational flux is upward.
1) Its magnet strength will be directed westward.
2) The [tex]\bar{V} \times \bar{B}[/tex] path is parallel to the east. The permanent magnet is oriented against the south so because the object is considered impolite.
3) Its gravitational field of the velocity v of the object is zero. Thus no force was its solution.
4) The magnetic field and velocity are all on the same track. The magnetic strength is also zero. Consequently, the answer is no power.
5) Its gravitational field is to the south.
6) Its magnetic field, as well as the speed, are different. Which magnet strength is also zero. Consequently, no power is the answer.
7) Accessible in French only. The [tex]\bar{V} \times \bar{B}[/tex] direction parallel to the east. Its magnetic energy is guided west because the particle is charged negatively.
8) Unless the particle velocity is 0, the magnetic strength is 0. Consequentl, no power is the response.
9) Its magnet power is from the north.
10) Another one of these: The [tex]\bar{V} \times \bar{B}[/tex] is parallel to the west. Its gravitational field is oriented to the east as the object is negatively charged.
11) The Pope said the following: The [tex]\bar{V} \times \bar{B}[/tex] direction is parallel to the south. The gravitational fluid is transmitted towards the North because a particle is considered impolite.
12) The gravitational field is from the east.

You continue standing on the scale when the elevator goes up, carefully watching the reading. During the trip to the 10th floor, the greatest scale reading was
Answers
Answer:
5.51 m/s^2
Explanation:
Initial scale reading = 50 kg
assume the greatest scale reading = 78.09 kg
Determine the maximum acceleration for these elevators
At rest the weight is = 50 kg
Weight ( F ) = mg = 50 * 9.81 = 490.5 N
At the 10th floor weight = 78.09 kg
Weight at 10th floor ( F ) = 78.09 * 9.81 = 766.11 N
F = change in weight
Change in weight( F ) = ma = 766.11 - 490.5 (we will take the mass as the starting mass as that mass is calculated when the body is at rest)
50 * a = 275.61
Hence the maximum acceleration ( a ) = 275.61 / 50 = 5.51 m/s^2

A man walks 40 m North, then 70 m East and then 40
m south. What is his displacement
from the starting point?
Answers
Answer:
Displacement = 70 m towards east
Explanation:
Displacement is the shortest distance between the two points.
Let us say that he starts at the point O and travels in a path ABC.
If we join the initial and final point of the path travelled by him, it will give the displacement of the man.
Distance from O to A = 40 m
Distance from A to B = 70 m
Distance from B to C = 40 m
Distance from O to A = Distance from B to C
We want the displacement which is distance between the points O and C
In rectangle opposite sides are equal. Hence Distance from O to C = Distance from A to B
Displacement = Distance from A to B

A) 4240 J
B) 8480 J
C) 2120 J
D) 1350 J
E) 2700 J
Answers
Answer:
B) 8480 J
Explanation:
From the question,
The work required to turn the Crank in on turn is
W = 2πT................ Equation 1
Where W = work, T = torque.
Given: T = 4.50 Nm, π = 3.14
Substitute into equation 1
W = 4.5(2)(3.14)
W = 28.26 J per turn.
For 300 full tern,
W = 28.26×300
W = 8476 J
Hence,
W≈ 8480 J.
The right answer is B) 8480 J

A uniform magnetic field with a magnitude of 1.40 T is perpendicular to the plane of the loop. If the balloon is blown up such that its diameter and the diameter of the wire loop increase to 31.0 cm in 0.048s, what is the magnitude of the average value of the emf induced in the loop
Answers
Answer:
EMF = 1.1929 V
Explanation:
In this case we need to use the following expression:
EMF = B *ΔA / t (1)
Where:
B: Magnetic field
ΔA: Difference of area of the balloon
t: time
To get the area, we have the innitial diameter of the balloon, and the expanded diameter when the balloon is blown up, so, assuming the circunference of the balloon, the area can be determined with:
A = π r² (2)
So, let's calculate the Area of the balloon before and after the blown. Remember to use the units in meter (I just divided the diameter by 2 to get the ratio, and then divide by 100 to convert the units of cm to m)
A₁ = π * (0.105)² = 0.0346 m²
A₂ = π * (0.155)² = 0.0755 m²
Now that we have both areas, let's calculate ΔA:
ΔA = A₂ - A₁
ΔA = 0.0755 - 0.0346 = 0.0409 m²
Finally, we can determine the value of the EMF, using (1):
EMF = 1.4 * 0.0409 / 0.048
EMF = 1.1929 VHope this helps
