A proton and a neutron are each close to a positive nucleus.
How does the charge on the nucleus affect the proton and the neutron, if at all?
A The neutron is attracted; the proton is repelled.
B The neutron is not affected; the proton is repelled.
C The proton is attracted; the neutron is repelled.
D The proton is not affected; the neutron is repelled.
Answer: b
Explanation:Because protons are positive and the nucleus is positive so it will be repelled and the neutron is neutral so it will be unaffected.

Multiply field strength (N/kg) by mass (kg) to get weight (N)
At the start, the car is carrying
4.7 kg * (9.8 N/kg) = 46.06 N
of fuel.
At the end, it is carrying
3.0 kg * (9.8 N/kg) = 29.4 N.
Assuming the car remains completely intact, its weight was reduced by
46.06 N - 29.4 N = 16.66 N.
Question 11 (3 points)
1. How many amperes does a 125 watt bulb require when operating on 12 volts?
a. 0.096 watts
b. 10.41 Watts
С. 10.41 Ampere
D. 1500 ampere
Answer:
С. 10.41 Ampere
Explanation:
Given that,
Power, P = 125 watts
Voltage, V = 12 volts
We need to find current. Power in terms of current and voltage is given by :
P = VI, I = current
[tex]I=\dfrac{P}{V}\\\\I=\dfrac{125\ W}{12\ V}\\\\I=10.41\ A[/tex]
So, the current is 10.41 A.
A toy car is given an initial velocity of 5.0 m/s and experiences a constant acceleration of 2.5 m/s2. What is the final velocity after 5.0 s?
a 21.6 m/s
b 19.2 m/s
c 17.5 m/s
d 24.5 m/s
Explanation:
v = u + at
v = 5 + 2.5 * 5
V ( final velocity after 5 sec) = 17.5 m/s

The one thing that they might do is making improvements to the original prototype in order to perform more tests. Thus option D is correct.
What is prototype?Prototype is defined as a type of early version, or initial release of a product created to test a theory or procedure.
It can be defined as a test procedure where design teams put concepts into concrete forms, whether they be paper or digital.
It can also be defined as a useful tool for the creation of new products. It provides the creative with the opportunity to watch their concept come to fruition.
There are three basic rule of prototyping.
Inquire as to who will gain.Fail frequently and early.Use show and ask instead of show and tell.When the EGL system code does not have access to the function itself, a function prototype definition is used to provide type checking on function calls.
Thus, the one thing that they might do is making improvements to the original prototype in order to perform more tests. Thus option D is correct.

Explanation:
You drive 200 miles in 3 hours before stopping for lunch and gas. After lunch you
travel 250 miles in an hour and a half What was your average speed in mi/hr)
for the trip
Given :
You drive 200 miles in 3 hours before stopping for lunch and gas. After lunch you travel 250 miles in an hour and a half.
To Find :
Average speed.
Solution :
We know, average speed is given by :
[tex]v=\dfrac{\text{Total distance covered}}{\text{Total time taken}}\\\\v=\dfrac{200+250}{3+1.5}\ miles/hr\\\\v=\dfrac{450}{4.5}\ miles/hr\\\\v=100\ miles/hr[/tex]
Therefore, average speed of the journey is 100 miles/hr.
Hence, this is the required solution.
Which represent correct variations of the formula for speed? Check all that apply. t = d/s s = d/t t = s/d s = dt d = st d = s/t
Answer: 1 2 5
Explanation:
Galileo Galilei, an Italian physicist, is credited with being the first to calculate speed by dividing it by the distance traveled and the time required. Galileo defined speed as the distance covered in a predetermined period of time. Thus option A, B. E is correct.
What represent correct variations of the formula for speed?Speed is determined by dividing the distance by the time. Calculating the units for speed requires knowledge of the units for both time and distance. Since the distance is measured in meters (m) and the time is measured in seconds, the units in this example will be meters per second (m/s) (s).
That is speed = distance time. Alternatively, you can calculate the time by dividing the distance traveled by the speed. You can figure out the third input if you know two of the inputs.
Therefore, For instance, if a car drives 120 miles (ca. 193 km) in 2 hours, we may calculate the speed as 120 × 2 = 60 miles per hour (ca. 97 km/h).

Texting and driving is a dangerous act
and is illegal in many areas. Suppose a driver takes 3.5 seconds to send a text. Travelling at 95 km/h, how far in meters did the vehicle travel while the driver was distracted? (Hint: How many seconds are in an hour?
How many meters are in a km?)
Answer:
s = 92.36 m
Explanation:
The distance covered by an object moving with uniform speed is given by the following formula:
s = vt
where,
s = distance covered by car during the time when driver was distracted in texting = ?
v = uniform speed of car = (95 km/h)(1 h/3600 s)(1000 m/1 km) = 26.39 m/s
t = time taken by the driver for texting = 3.5 s
Therefore, using these values in equation, we get:
s = (26.39 m/s)(3.5 s)
s = 92.36 m

What is the momentum of A 200 kg shark swimming at 15 m/s? bruh please help im failing and dont understand this:)
Answer:
p = 3000 kg-m/s.
Explanation:
Given that,
Mass of shark, m = 200 kg
Speed of the shark, v = 15 m/s
We need to find the momentum of the shark. It can be calcullated as follows :
p = mv[tex]p=200\ kg\times 15\ m/s\\\\p=3000\ kg-m/s[/tex]
So, the momentum of the shrak is 3000 kg-m/s.
A bird flies 6km east, then 4km west. Find the total distance traveled and displacement (d) after this flight.
Given :
A bird flies 6 km east, then 4 km west.
To Find :
the total distance traveled and displacement after this flight.
Solution :
a)
We know , total distance is the amount of how much ground an object has covered .
Distance = 6+4 km = 10 km .
b )
Displacement is the shortest distance from one point to another .
Now , here the object first move 6 km east then moves 4 km west .
So , his distance from the starting position is :
Displacement = 6 - 4 km = 2 km .
Hence , this is the required solution .

Which action might lead scientists to develop new explanations about the universe?
Answer:
Designing experiments to replicate the conditions in which life may have first evolved on Earth
Explanation:
In 1953, Stanley L. Miller and Harold C. Urey conducted an experiment to prove that life started from inanimate objects. The research was conducted by utilizing proposed chemical substances, mixed together through a scientific design process. The outcome of the research is the predicted atmospheric conditions before the pre-living form started on earth.
Therefore, in this case, the action that might lead scientists to develop new explanations about the universe is "Designing experiments to replicate the conditions in which life may have first evolved on Earth."

No, not any of these substance will float in Methanol , simply because Methanol has a density of 0.79 g, if you put any substance that weighs more than 0.79 g, it will sink, it all depends on the weight if it is more or less than methanol
2: D=m/v
D=135/50 = 2.7 g/cm³ ( Aluminum)
D=M/V
if two objects has the same mass but one has larger volume, then te one with larger volume has less density
example : 2 objects
mass of both=350
volume of the first one=500 and the other 750
D1=M1/V1 = 350/500 =0.7
D2 = M2/V2 = 350/750 = 0.4666
D1 is larger than D2( with larger volume )
As the earth rotates through one revolution, a person standing on the equator traces out a circular path whose radius is equal to the radius of the earth (6.38×10^6). What is the average speed of this person in meters per second? If we are standing in latitude 43° north what is our average speed?
Answer:
The average speed will be "1038 mph".
Explanation:
Period for one revolution is:
T = 24 hours
= 86,400 sec
x = c = 2πr
The given values is:
r = 6.38×10⁶ m
Now,
⇒ [tex]T=\frac{2 \pi r}{v}[/tex]
Or,
⇒ [tex]v=\frac{2 \pi r}{T}[/tex]
On substituting the values, we get
[tex]=\frac{2 \pi (6.38\times 10^6)}{86,400}[/tex]
[tex]=464 \ min/sec[/tex]
[tex]=(464 \frac{min}{sec}) (\frac{3600 \ sec}{1 \ hour} )(\frac{1 \ mi}{1609 \ m} )[/tex]
[tex]=1038 \ mph[/tex]
