Answer:

Explanation:

1. A measure of how quickly velocity is changing is the acceleration

Acceleration is the rate of change of velocity with time. The rate at which a body is changing its velocity is known as the acceleration.

It is measured in the unit m/s²

2. Speed in a given direction is the velocity

Velocity is a vector quantity which measures the magnitude of motion in a specific direction. It is simply speed in a given direction.

When we say a motorcycle travels at the rate of 5m/s due east, we are describing the velocity of such body.

3. Force that resists moving one object against another is the friction

Friction is a force that opposes motion. It prevents a body from moving.

4. Measure of the pull of gravity on an object Weight

Weight is a measure of the amount of gravitational force on a body. It is mathematically expressed as;

         W = mg

W is the weight, m is the mass and g is the acceleration due to gravity

5 Tendency of an object to resist a change in motion is inertia

Inertia is the tendency of body to resist change in motion. It is the ability of a body to remain in a perpetual state of rest.

6 Size is the magnitude

1 kg of water (specific heat = 4184 J/(kg K)) is heated from freezing (0°C) to boiling (100°C). What is the change in thermal en
Andrews [41]

Answer: 1560632 joules

Explanation:

The change in thermal energy (Q) required to heat ice depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

Given that:

Q = ?

Mass of frozen water (ice) = 1kg

C = 4184 J/(kg K)

Φ = (Final temperature - Initial temperature)

= 100°C - 0°C = 100°C

Convert 100°C to Kelvin

(100°C + 273) = 373K

Then, Q = MCΦ

Q = 1kg x 4184 J/(kg K) x 373K

Q = 1560632 joules

Thus, the change in thermal energy is 1560632 joules

Which correctly describes the reaction between potassium and excess water?
nika2105 [10]
Balanced chemical reaction: 2K(s) + 2H₂O(l) → 2KOH(aq) + H₂(g).

KOH is inorganic compound p<span>otassium hydroxide, a strong base.
H</span>₂ is hydrogen gas.
In balanced chemical reaction number of atoms on both side of chemical reaction must be same. There are two potassium atoms, four hydrogen atoms and two oxygen atoms on both side of reaction.

Identify the substances that will appear in the equilibrium constant expression for the equation: 2Ag+(aq)+Zn(s)&lt;-&gt;Zn2+(aq
Simora [160]

Hey there!


We Know that:



 2 Ag⁺(aq) + Zn(s) <-> Zn²⁺(aq)+2 Ag(s)


The equilibrium expression for the reaction is:



Kc =  [ Zn⁺² ]  /  [Ag⁺ ]²


Hope that helps!
