Zepler [3.9K]4 years ago
8 0

Answer:

The rate of change in the velocity of an object per unit time is referred as acceleration and the kind of motion is known as accelerated motion. The acceleration is positive when it is in the direction of velocity and negative when it is opposite to the direction of velocity.

Give real-world examples of evidence that supports the evolution of Earth in each category:
laila [671]

Answer:

real world examples

Explanation:

concave wave rock- The wave rock is formed by weathering of the surrounding area, which helps in proving the deposition part, as the wave rock was below the ground, occurred due to deposition of rock years over years. It is made from very tough material from its surrounding. The weathering reduced the surrounding terrain, while the bedrock remained to witness for the history.  --Also, volcanic eruptions have changed earth greatly. EX- Ash and sulfur went into Earth's atmosphere because of the Tambora eruption which dimmed incoming sunlight. It lowered global temperatures by about 3°F. The Mount Pinatubo of 1991 that erupted in the Philippines cooled the planet by about 1°F.

The voltage or potential difference provides the ____ required for electrons to travel through a circuit
galben [10]

Answer:

a. push

Explanation:

Voltage is the force or pressure that is responsible for pushing the charge or electrons to flow in a closed-looped electrical circuit. This flow of electrons (charge) is called the electric current. It is also defined as the difference in electric potential per unit charge between two points in an electric field.

Calculate the amount of heat needed to increase the temperature of 200 grams of water at 10°C to 95°C.
Alexus [3.1K]

the amount of heat need is 71060 Joules

Explanation

The equation for the amount of heat needed to increase the temperature of water is as follows:

\begin{gathered} E=mC(T_2-T_1) \\ where \\  \\  \end{gathered}

where E is the amount of heat

C is the specific heat capacity of water having a standard value of 4180 J/kg*K

T is the final ans initial temperature in kelvin

m is the mass

so

Step 1

given

\begin{gathered} mass=m=200\text{ gr=0.2 kg} \\ T_1=10\text{ \degree C} \\ T_2=95\text{ \degree C} \\ C=4180\text{ J/kh*K} \end{gathered}

a) convert the temperature into kelvin

\begin{gathered} 10\text{ \degree C=\lparen10+273\rparen K=283 K} \\ 95\text{ \degree C=\lparen95+273 \rparen K=368 K} \end{gathered}

now, replace in the formula

\begin{gathered} E=mC(T_{2}-T_{1}) \\ E=0.2\text{ kg*4180L/kg*K*\lparen368K-283 k\rparen} \\ E=71060\text{ J} \end{gathered}

therefore, the amount of heat need is 71060 Joules

I hope this helps you
