Answer:

50N

Explanation:

Force (N) = mass (kg) × acceleration (m/s²)

0.25kg times 200m/s² = 50N

Answer:

3.16kgm/s

Explanation:

Given parameters:

Mass  = 770g

Velocity  = 4.1m/s

Unknown:

Momentum of the car  = ?

Solution:

To solve this problem, we use the equation below:

       Momentum  = mass x velocity

Convert the mass to kg;

        770g to kg = 0.77kg

Now;

    Momentum  = 0.77 x 4.1  = 3.16kgm/s

Answer:

B. 2

Explanation:

The reaction expression is given as:

                _S  + 3O₂   →  2SO₃

Now let us balanced the expression;

  On the product side we have 2 moles of S

   On the reactant side we should have 2moles of S

So, we put the coefficient 2 to balance the expression;

   We have 6 moles oxygen on both sides

Answer:

4. Wx = 42.47[N]

Explanation:

In order to solve this problem, we must first make a free body diagram, of the forces acting on the body in the inclined plane.

As we can see in the attached image, the component of the weight parallel to the surface of the inclined plane can be obtained by the sine of the angle.

Answer:

C. Acid

Explanation:

If you have chemistry classes and performed experiments regarding acids and bases, you would physically tell it's acid if the lithmus paper turned red and base if it turned blue. Also, in the pH level chart, there are only two characteristics--acidic and basic. Since it has less than 7 pH, it is definitely acid. Plus, remember the taste of some vitamin C tablets? It has a sour taste to it, isn't it? This is because of ascorbic acid.

The given properties are indicating the substance is acid. Therefore, option (C) is correct.

An acid can be described as any substance that is capable of losing a proton to another substance.  A base can be described as a molecule or ion that can accept a hydrogen ion from an acid.

Acidic substances can be identified by their sour taste. Acid is usually a molecule that donates an H⁺ ion and can be energetically favorable after a loss of an H⁺ ion. Acids are also capable to turn blue litmus into the red.

Bases can be characterized by a slippery texture and a bitter taste. A base that can be dissolved in water as an alkali. When bases and acids react, they form salts and water. Bases can turn red litmus into blue.

The acid reacts vigorously with most metals to form hydrogen. Acidic substances have pH of less than 7.

Answer:

Vf = 99.7 m/s

Explanation:

In order to find the final velocity of the car, we will use the third equation of motion. The third equation of motion is given as follows:

[tex]2as = V_{f}^{2} - V_{i}^{2}[/tex]

where,

a = acceleration of the car = 9.2 m/s²

s = distance traveled by the car = 540 m

Vf = Final Speed of the car = ?

Vi = Initial Speed of the car  1.6 m/s

[tex]2(9.2\ m/s^{2})(540\ m) = (V_{f})^{2}-(1.6\ m/s)^{2}\\V_{f}^{2} = 9936\ m^{2}/s^{2} + 2.56\ m^{2}/s^{2}\\\\V_{f} = \sqrt{9938.56\ m^{2}/s^{2}}[/tex]

Vf = 99.7 m/s

33.33Watts

Explanation:

Given parameters:

Work done  = 1000J

Time taken  = 30s

Unknown:

Power  = ?

Solution:

To solve this problem, we must understand that power is the rate at which work is done.

So;

       Power  = [tex]\frac{Work done }{time}[/tex]  

Now insert the parameters:

 Power = [tex]\frac{1000}{30}[/tex]     = 33.33Watts
