Answer:

Magnitude of the force on proton = F = 1.1085 × 10^-15 N

Explanation:

Charge on proton = q = 1.60 × 10^-19 C

Velocity of proton = V = 4.0 × 10^4 m/s

Magnetic field = B = 0.20 T  

Angle between V and B = θ = 60

We know that,  

F = qVBsin θ = (1.60 × 10^-19)( 4.0 × 10^4)( 0.20)sin(60)

F = 1.1085 × 10^-15 N

The magnitude of the magnetic force on the proton is 1.1 × 10⁻¹⁵ N

\texttt{ }

<h3>Further explanation</h3>

<em>Let's recall </em><em>magnetic force on moving charge</em><em> as follows:</em>

\boxed{F = B q v \sin \theta}

<em>where:</em>

<em>F = magnetic force ( N )</em>

<em>B = magnetic field strength ( T )</em>

<em>q = charge of object ( C )</em>

<em>v = speed of object ( m/s )</em>

<em>θ = angle between velocity and direction of the magnetic field </em>

Let's tackle the problem now !

\texttt{ }

<u>Given:</u>

speed of proton = v = 4.0 × 10⁴ m/s

magnetic field strength = B = 0.20 T

charge of proton = q = 1.60 × 10⁻¹⁹ C

direction of speed = θ = 60°

<u>Asked:</u>

the magnitude of the magnetic force on the proton = F = ?

<u>Solution:</u>

F = B q v \sin \theta

F = 0.20 \times 1.60 \times 10^{-19} \times 4.0 \times 10^4 \times \sin 60^o

F = 6.4\sqrt{3} \times 10^{-16} \texttt{ N}

\boxed{F \approx 1.1 \times 10^{-15} \texttt{ N}}

**Fill in the blanks**
Nataly_w [17]

Answer:

Word for the first blank: gravity

Word for the second blank: matter

Explanation:

The only way debris from the impact with Earth can be held close to Earth is due to a force. The only force that could be acting from Earth is "the force of gravity".

The gravitational pull of this new object being formed, increases proportional to its mass as more and more "matter" accumulates. And the accretion process is now on its way.

 Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.Displacement<span> is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

</span>To calculate displacement<span>, simply draw a vector from your starting point to your final position and solve for the length of this line. If your starting and ending position are the same, like your circular 5K route, then your </span>displacement<span> is 0. In physics, </span>displacement<span> is represented by Δs.
 
 For me to solve this I would need to know the time, but I can give you a handy displacement calculator I used that helped me.

Sam is recklessly driving 60 mph in a 30 mph speed zone when he suddenly sees the police. he steps on the brakes and slows to 30
barxatty [35]
For this problem, we use the derived equations for rectilinear motion at constant acceleration. The equations used for this problem are:

a = (v - v₀)/t
2ax = v² - v₀²
where
a is the acceleration
x is the distance
v is the final velocity
v₀ is the initial velocity
t is the time

The solution is as follows;

a = (60mph - 30 mph)/(3 s * 1 h/3600 s)
a = 36,000 mph²

2(36,000 mph²)(x) = 60² - 30²
Solving for x,
x = 0.0375 miles

Nady [450]
It is a completely false statement that in <span>any energy transformation, there is always some energy that gets wasted as non-useful heat. The correct option among the two options that are given in the question is the second option. I hope that this is the answer that has actually come to your desired help.</span>
