If an element an atomic number of 32 and a mass of 72, how many neutrons does it have?

Answer:

4.27m

Explanation:

Recall that for uniform rotational motion,

the formula for centripetal acceleration is given as

Centripetal acceleration = ( velocity)² / radius

in our case we are given :

Centripetal acceleration = 9.0 m/s²

velocity = 6.2 m/s

substituting these into the formula:

9.0 = 6.2² / radius

radius = 6.2² / 9.0 = 4.27m

Answer:

B.Ionizing radiation is the correct answer.

Explanation:

Ionizing radiation has sufficient energy that it can convert atoms and molecules into ions.

It has a sufficient amount of energy that it can separate tightly confined electrons from the orbit of an atom and causing that atom to become ionized.

Answer: lonizing radiation

Answer:

X = 2146.05 m

Explanation:

We need to understand first what is the value we need to calculate here. In this case, we want to know how far from the starting point the package should be released. This is the distance.

We also know that the plane is flying a certain height with an specific speed. And the distance we need to calculate is the distance in X with the following expression:

X = Vt   (1)

However we do not know the time that this distance is covered. This time can be determined because we know the height of the plain. This time is referred to the time of flight. And the time of flight can be calculated with the following expression:

t = √2h/g   (2)

Where g is gravity acceleration which is 9.8 m/s². Replacing the data into the expression we have:

t = √(2*2500)/9.8

t = 22.59 s

Now replacing into (1) we have:

X = 95 * 22.59

This is the distance where the package should be released.

Hope this helps

Answer:

Only the goalie is allowed inside the goal crease. The only exception when another player is allowed in the goal area is when they take off from outside the goal area, and shoots or passes the ball before landing. To avoid interference with other players, the player must then exit the goal area as soon as possible.

Answer:

the final velocity of the object is 53.04 m/s.

Explanation:

Given;

initial velocity of the projectile, u = 50 m/s

displacement of the object, d = 16 m

let the final velocity of the object = v

Apply the following kinematic equation to determine the final velocity of the projectile.

v² = u² + 2gd

v² = 50² + (2 x 9.8 x 16)

v² = 2813.6

v = √2813.6

v = 53.04 m/s

Therefore, the final velocity of the object is 53.04 m/s.

Answer:

The first egg is thrown at a wall and breaks because it has no time to decelerate and it breaks.

While, when a second egg is thrown at wall with same velocity and collides with a bed sheet, it does not break because it get more time to decelerate  or collide with the wall.  It reduces the amount of force exerted on the egg and it does not break.

Answer:

Energy:Energy is defined as the ability to do work.Example:Light energy,heat energy etc

Work:When force is applied on an object and it dispaces in the direction of that force then it is said that work has done.Its SI unit is joule

Power:Power is defined as the ratio of work done to the total time.Its SI unit is watt

Answer:

The car will travel the distance of 15 miles

S= D/T

therefore

D=ST

D = Distance

S = Speed (30 mph)

T = Time (0.5 Hours)

D = 30 * 0.5 = 15

Answer:

Follows are the solution to the given question:

Explanation:

For point a:

[tex]T= 2\pi \sqrt{\frac{m}{k}}\\\\k = \frac{4 \pi^2 m}{T^2}\\\\= \frac{4 \times (3.14)^2 \times 3}{2^2}\\\\=29.578 \ \frac{N}{m}\\\\[/tex]

For Point b:

[tex]E=\frac{1}{2} m a^2 w^2\\\\[/tex]

   [tex]=\frac{1}{2} \times m \times a^2 \times \frac{4\pi^2}{T^2}\\\\=\frac{1}{2} \times 3 \times (0.15)^2 \times \frac{4\times 3.14^2}{2^2}\\\\=0.332 \ J[/tex]

For Point C:

[tex]V_{max}= a w[/tex]

        [tex]= (0.15) \times \frac{2\pi}{T}\\\\= (0.15) \times \frac{2\times 3.14}{2}\\\\=0.471 \frac{m}{s}[/tex]

For point D:

[tex]X= a \sin (wt+ \phi)\\\\0.91=0.15 \sin(\frac{2\pi}{T} \times t+\phi)\\\\0.91=0.15 \sin(\frac{2\times 3.14}{2} \times 0.5+\phi)\\\\0.60 = \sin(3.14 \times 0.5+\phi)\\\\0.60 = \sin(1.57+\phi)\\\\1.57 +\phi =\sin^{-1} 60^{\circ}\\\\1.57 +\phi = 36.86^{\circ}\\\\=35.29^{\circ}\\\\So, X=15 \sin(3.14t+35.29^{\circ}) \ cm[/tex]

Time for speed walking  = 10min

Speed  = 13.63?

Unknown:

Distance you can speed walk  = ?

Solution:

To solve this problem, we simply apply the velocity - time equation;

 Speed  = [tex]\frac{distance}{time}[/tex]  

 Distance  = speed x time

make sure you speed and time are in the same unit

 Insert the parameters and solve

Answer:

To change.

Explanation:

The Law of Conservation of energy states that energy cannot be destroyed but can only be transformed or converted from one form to another. For example, light energy to heat energy.

When a material absorbs energy from light the energy causes the material to change.

Explanation:

Answer:

118.4kgm/s

Explanation:

Given parameters:

Weight of object  = 19.6N

          mass of object  = 19.6/9.8   = 2kg

Constant velocity  = 20m/s

Force applied  = 6N

Time taken  = 4s

Unknown:

Final momentum of the object  = ?

Solution:

To solve this problem, we use Newton's second law of motion;

           Ft  = m (v  - u)

F is the force applied

t is the time taken

m is the mass

v is the initial velocity

u is the time taken

           Ft  = mv  - mu

mv is the final momentum;

       So;

     Final momentum  = Ft + mu

 Final momentum  = (19.6 x 4) + (2 x 20) = 118.4kgm/s
