Neither are Strong acid.

<h3>What does “strong acid” mean?</h3>

In the solution, solid acids entirely separate into ions. For instance, hydrochloric acid is a solid acid.

It totally ionizes, forming hydrogen and chloride ions. Nitric acid and sulfuric acid are also components of strong acids.

A solid or strong acid is one that has completely dissociated into ions. It is a weak acid if it does not dissociate completely.

<h3>What is an example of a strong acid?</h3>

Chloric acid, hydrobromic acid, hydrochloric acid, hydroiodic acid, nitric acid, perchloric acid, and sulfuric acid are the seven major acids that make up strong acids. These are referred to as strong acids since they can totally dissociate in water.

What is the acceleration of a rock at the top of its trajectory when thrown straight upward. explain whether or not the answer i

zvonat [6]

The acceleration of the rock is the gravitational acceleration due to earth which is around 9.8 m/s^2. As the rock travels upwards it is working against the constant force of gravity and when it reaches the top it is the force of gravity that will cause a cause in the direction of the rocks velocity and cause it to accelerate towards earth. Using the equation a = F/m, the acceleration due to gravity exerts a force per unit mass on an object causing the object to accelerate, anything above earth surface will therefore have an external gravitational force action on it (in terms of projectile motion). So at the top of the rocks trajectory, the acceleration of the rock will be g (9.8) as a constant force is gravity is exerted on the rock throughout its path.

On land, coal is transported primarily by train. A typical large coal train may be about 1.5 km long and may consist of 120 cars

WINSTONCH [101]

Answer:

equivalent power = 6.60 × $10^{12}$ W

Explanation:

given data

coal train length = 1.5 km = 1500 m

contain = 120 cars

holding= 110 tonnes of coal each

train traveling speed = 100 km/h = 27.78 m/s

to find out

equivalent power in watts

solution

we take here energy produce by coal is 27 × $10^{6}$ J/kg

and here total coal = 120 × 110 × 10³ kg

sop here energy produce by total coal is

energy produce by total coal = 27 × $10^{6}$ × 120 × 110 × 10³

and time required to cross that distance is

time = $\frac{distance}{speed}$

time = $\frac{1500}{27.78}$

time = 53.99 sec

so here equivalent power will be

equivalent power = $\frac{energy}{time}$

equivalent power = $\frac{27*10^6*120*110*10^3}{53.99}$

equivalent power = 6.60 × $10^{12}$ W

A solid sphere of radius R is made of an insulating material. It holds a charge, Q, which is distributed evenly throughout the s

Vinvika [58]

Answer:

The magnitude of Electric Field is $E=\dfrac{Qr}{4\pi \epsilon_0 R^3}$

Explanation:

Given:

Radius of the solid sphere=R
Total charge of the sphere=Q

Let consider a Gaussian surface at a distance of r such that 0<r>R in the shape of sphere such that the electric Field due to this E and it is radially outwards.

The charge inside this Gaussian surface volume we have , $q_{in}=\dfrac{Qr^3}{R^3}$

Now using Gauss Law we have

$E\times4\pi r^2=\dfrac{q_{in}}{\epsilon_0}\\E\times4\pi r^2=\dfrac{\dfrac{Qr^3}{R^3}}{\epsilon_0}\\E=\dfrac{Qr}{4\pi \epsilon_0 R^3}$
