use thermal energy in a sentence.
Answer:
please mark brainliest!
Explanation:
here are a few examples-
- The heat gives off subtle infrared rays which produce thermal energy to heat the floor.
- In the space of only a few nanoseconds, a great deal of magnetic energy is converted into the thermal energy of the plasma.
- Although there have been some changes in the thermal energy in the park since 1871, there has been no appreciable diminution.
- Hence a part of what must be included in thermal energy is not simply proportional to temperature as is commonly assumed.

Answer the above questions and give an example of a cause and effect relationship. See if you can think up a cause and effect relationship using acids, bases, and neutralization.
Answer:
C. would be the correct option
Explanation:
Burning gasoline is a chemical change because when gasoline is ignited, water and carbon dioxide are produced. Water freezing to form ice would be a physical change since its state of matter has changed, but not the water itself. Sugar dissolving in water is also a physical change because all it's really doing is just forming bubbles and changing the color. Choice D. would also be a physical change since the piece of metal is still a piece of metal, it just expanded when the temperature increased.

Look at the symbol. Which component in a circuit does it represent?
A. resistor
B. switch
C. AC power source
D. DC power source
Answer:
Resistor
Explanation:
a device having a designed resistance to the passage of an electric current.
As per the symbol in the figure, the component in a circuit it represents is a resistor. Hence, option A is correct.
What is a resistor?Electrical resistance is implemented as a circuit element by resistors, which are passive two-terminal electrical components. Resistors are devices that are used in electronic circuits for a variety of purposes, including lowering current flow, adjusting signal levels, dividing voltages, biasing active components, and terminating transmission lines.
As parts of motor controllers, power distribution networks, or even as for that for generators, rising resistors that really can dissipate several watts of electrical energy as heat may be used. When operating at a given temperature, time, or voltage, a fixed resistor's resistance only minimally varies.
In addition to being utilized as circuit element adjusters, variable resistors can also be used as sensors for chemical, force, heat, light, and humidity activity. Electronic equipment is rife with resistors, which are common components of electronic circuits and electrical networks.

If an object is moving at 4 m/s in the x-direction, and 2 m/s in the y-direction, what is the velocity of the object written in terms of standard basis vectors?
Answer:
V = 4i^ + 2j^
Explanation:
We are given;
Velocity in the x-direction; V_x = 4 m/s
Velocity in the y-direction; V_y = 2 m/s
Now, in terms of standard basis vectors, we normally write the resultant velocity as;
V = (V_x)i^ + (V_y)j^
Thus, the resultant velocity is;

Pedro and Perla are grocery shopping. Pedro throws a banana at Perla to get her attention. Perla picks up a cantaloupe, which is 5 times heavier, and throws it at Pedro with the same speed that he threw the banana. How much more kinetic energy does the cantaloupe have
Answer:
The cantaloupe has a kinetic energy that is 5 times that of the banana.
Explanation:
Kinetic energy (KE) = [tex]\frac{1}{2}[/tex]m[tex]v^{2}[/tex]
where m is the mass of the object and v its velocity.
For the banana, let its mass be represented by m and its velocity by v.
So that:
Kinetic energy of the banana = [tex]\frac{1}{2}[/tex]m[tex]v^{2}[/tex]
For the cantaloupe, given that its mass is 5 times that of banana (5m) but has the same speed as that of banana.
Then,
kinetic energy of the cantaloupe = [tex]\frac{1}{2}[/tex] 5m[tex]v^{2}[/tex]
= [tex]\frac{5}{2}[/tex]m[tex]v^{2}[/tex]
= 5([tex]\frac{1}{2}[/tex]m[tex]v^{2}[/tex])
= 5 x kinetic energy of the banana
The cantaloupe has a kinetic energy that is 5 times that of the banana.
A projectile is launched at an angle of 45 degrees with a velocity of 250 m/s. If air resistance is neglected, the magnitude of the horizontal velocity of the projectile at the time it reaches maximum altitude is equal to
Answer:
The horizontal velocity of the projectile at the time it reaches maximum altitude approximately equal to 131.331 meters per second.
Explanation:
From Mechanical Physics we understand that projectile motion is the combination of a horizontal motion at constant velocity and a vertical uniform accelerated motion due to gravity. Then, the horizontal velocity of the projectile ([tex]v_{x}[/tex]), measured in meters per second, remains constant during motion. That is:
[tex]v_{x} = v_{o}\cdot \cos \theta[/tex] (Eq. 1)
Where:
[tex]v_{o}[/tex] - Initial velocity of the projectile, measured in meters per second.
[tex]\theta[/tex] - Launch angle above the horizontal, measured in sexagesimal degrees.
If we know that [tex]v_{o} = 250\,\frac{m}{s}[/tex] and [tex]\theta = 45^{\circ}[/tex], then horizontal velocity of the projectile at the time it reaches maximum altitude is:
[tex]v_{x} = \left(250\,\frac{m}{s} \right)\cdot \cos 45^{\circ}[/tex]
[tex]v_{x} \approx 131.331\,\frac{m}{s}[/tex]
The horizontal velocity of the projectile at the time it reaches maximum altitude approximately equal to 131.331 meters per second.

Gina is sitting by a stream. She sees a clam shell on the bottom of the stream. An acorn falls in the stream and floats on the water. A wooden stick also floats by. Which object that Gina saw has the greatest density? A. Wooden stick, B. Clamshell, C. Acorn, D. Water
Answer:
B. Clamshell
Explanation:
Density is defined as mass per volume. The density of an object decides whether that object will sink or float if placed in water.
An object with higher density sinks in the water while an object with less density floats in water. In the given example, Clamshell has the highest density as it sinks in the water while other objects' wooden stick and acorn float over the water.
Clamshell has the highest density than water as well because the object has more weight per unit of volume and the buoyancy force of water decreases that allow the object to sink.
Hence, the correct answer is "B. Clamshell".

Answer:
12.5 m/s
Explanation:
Given that,
The initial horizontal and vertical components are 12.50 m/s and 21.70 m/s, respectively.
We need to find the horizontal velocity of the ball at position C.
It is a case of projectile motion. We know that in case of projectile motion, the horizontal velocity of the projectile remains the same while vertical velocity varies. It can be very clear that the horizontal velocity at C is 12.5 m/s.
