True or False?
tangare [24]

The correct answer is; False.

Further Explanation:

Ash does not remain in the atmosphere for years after an eruption. It only takes a few days or at the most a few weeks for all of the ash to leave the atmosphere. It has little impact on the climate or global temperatures.

When a volcano erupts there are three things that the volcano puts out, they are;

  1. Ash
  2. Lava
  3. Sulfur dioxide (SO2)

The one thing that does have an effect on the global temperatures of an eruption is the volcanic aerosols. These aerosols, when released, reflect the solar radiation back to space.

A cat rides a merry-go-round while turning with uniform circular motion. At time t1 = 2.00 s, the cat's velocity is v with arrow
DiKsa [7]

Answer:

(a)

a_c=3.41\frac{m}{s^2}

(b)

a_a_v_g=0\frac{m}{s^2}

Explanation:

Let's calculate the magnitude of cat's velocity at time t1 and time t2:

At\hspace{3}t_1

|v_1|=\sqrt{(v_x)^{2}+(v_y)^{2}  } =\sqrt{(1.70)^{2}+(4)^{2}  } =4.346262762m/s

At\hspace{3}t_2

|v_2|=\sqrt{(v_x)^{2}+(v_y)^{2}  } =\sqrt{(-1.70)^{2}+(-4)^{2}  } =4.346262762m/s

For now:

|v_1|=|v_2|

So, we can assume that cat's tangential velocity is constant. Now, considering that the time T required for one complete revolution is called the period. For  constant speed is given by:

T=\frac{2*\pi *r}{v}  (1)

Where:

r=radius\hspace{3}of\hspace{3}curvatrue

v=tangential\hspace{3}velocity

The problem tell us that at time t2=4 the cat has completed a half-revolution, so we can conclude that the cat complete a revolution in 8s, T=8s. Replacing the data in (1) and isolating r:

r=\frac{T*v}{2*\pi} =\frac{8*4.346262762}{2*\pi}=5.533833621m

Now the centripetal acceleration is given by:

a_c=\frac{v^{2} }{r} =\frac{(4.346262762)^{2} }{5.53383621} =3.413546791m/s^2

Finally, The average acceleration is the final velocity minus the initial velocity per time taken.

a_a_v_g=\frac{\Delta v}{\Delta t} =\frac{v_2-v_1}{t_2-t_1} =\frac{4.346262762-4.346262762}{4-2}=\frac{0}{2} =0

Which of the following statements best describes the definition of<br> distance?
ch4aika [34]

Explanation:

  • The distance covered by a body is equal to the sum of total path covered. It is equal to the total path traveled by an object during its entire journey.
  • This quantity is always positive. It can't be 0 or a negative number.
  • It is defined as a scalar quantity.
  • Mathematically, it can be calculated as follows :

distance = speed × time

A capacitor consists of a set of two parallel plates of area a separated by a distance
MakcuM [25]
When a dielectric material is inserted between two plates of capacitor that are connected to a battery, you would observe that both the charge and the capacitance of the capacitor would change. This is due to the dielectric material which is able to transmit electric force.
