Answer:

Combination or synthesis

Explanation:

The reaction is a combination or synthesis reaction in which two or more substances combines to give a single product.

In such a reaction there is formation of compounds from the union of their constituent elements.

The driving force for such reactions is the large and negative heat of formation of the product.

So, this is a combination reaction.

Allushta [10]

The total mechanical energy is the sum of the kinetic energy and the gravitational potential energy:
$E=K+U= \frac{1}{2}mv^2 +mgh$
where m=3.5 kg is Candy's mass, v=1 m/s is her velocity and h=3.5 m is her height. If we replace these numbers, we find the mechanical energy of the system:
$E= \frac{1}{2} (50 kg)(1m/s)^2 + (50 kg)(9.81 m/s^2)(3.5 m)=1742 J =1.74 kJ$

A parallel-plate capacitor in air has circular plates of radius 2.8 cm separated by 1.1 mm. Charge is flowing onto the upper pla

Hatshy [7]

Answer:

The time rate of change of the electric field between the plates is $\frac{E }{t} = 2.29 *10^{14} \ N \cdot C \cdot s^{-1}$

Explanation:

From the question we are told that

The radius is $r = 2.8 \ cm = 0.028 \ m$

The distance of separation is $d = 1.1 \ mm = 0.0011 \ m$

The current is $I = 5 \ A$

Generally the electric field generated is mathematically represented as

$E = \frac{q }{ \pi * r^2 \epsilon_o }$

Where $\epsilon_o$ is the permitivity of free space with a value

$\epsilon_o = 8.85*10^{-12 }\ m^{-3} \cdot kg^{-1}\cdot s^4 \cdot A^2$

So the time rate of change of the electric field between the plates is mathematically represented as

$\frac{E }{t} = \frac{q}{t} * \frac{1 }{ \pi * r^2 \epsilon_o }$

But $\frac{q}{t } = I$

$\frac{E }{t} = * \frac{I }{ \pi * r^2 \epsilon_o }$

substituting values

$\frac{E }{t} = * \frac{5 }{3.142 * (0.028)^2 * 8.85 *10^{-12} }$

$\frac{E }{t} = 2.29 *10^{14} \ N \cdot C \cdot s^{-1}$

A skateboarder is moving at a constant speed of

Flauer [41]

The amount of time that passes from when this skateboarder begins to slow down until she begins to move back down the incline is 8.75 seconds.

<u>Given the following data:</u>

Speed = 1.75 m/s

Acceleration = -0.2 $m/s^2$

To calculate the amount of time that passes from when this skateboarder begins to slow down until she begins to move back down the incline, we would apply the first equation of motion;

<h3>The formula for the first equation of motion.</h3>

Mathematically, the first equation of motion for a decelerating object is given by this formula;

$V=U-at$

<u>Where:</u>

a is the acceleration.

V is the final speed.

U is the initial speed.

t is the time measured in seconds.

Substituting the given parameters into the formula, we have;

$1.75 = 0-(-0.2)t\\\\1.75=0.2t\\\\t=\frac{1.75}{0.2}$

Time, t = 8.75 seconds.
