Find the speed of a wave (in meters/second) whose wavelength is 4 meters and
whose frequency is 3.5 Hz. Enter a number rounded to the first decimal place
(e.g. "0.1").
Your answer
Wave speed = (wavelength) x (frequency)
Wave speed = (4 m) x (3.5 /s)
Wave speed = 14.0 m/s

It's 2:30 pm in India, when it's 12:00 pm in London. So if I travel from India to London in one second, will I time travel?
Answer:
No and yes
Explanation:
Yes technically you are time traveling.
But not in the way like the movies or whatever when they go to 1956 or whatever.
You are time traveling because you are going from 2:30 to 12:00. And you are traveling :|
But no because. . . just no :\

Brainliest whoever answers first!!! and right!!! Identify the situations that have an unbalanced force. Check all that apply. a weight speeds up as it falls through the air a garbage can is at rest on the ground a hockey puck moves in a straight line at a constant speed a bumper car hit by another car moves off at an angle a balloon flies across the room when the air is released
Answer:
its A,D,E
Explanation:
I got 2 right one of them wrong
Answer:
A baseball speeds up as it falls through the air.
Yes. Forces on the balloon are unbalanced.
The balloon is speeding up, so we know that the downward force
of gravity is stronger than the upward force of air resistance.
A soccer ball is at rest on the ground.
No. The ball is not accelerating, so we know that the forces on it
are balanced.
The downward force of gravity on the ball and the upward force
of the ground are equal.
An ice skater glides in a straight line at a constant speed.
No. The skater's speed and direction are not changing, so he is not
accelerating. That tells us that the forces on him are balanced.
A bumper car hit by another car moves off at an angle.
Yes. The direction in which the car was moving changed.
That's acceleration, so we know that the forces on it are unbalanced,
at least at the moment of impact.
A balloon flies across the room when the air is released.
Yes. The balloon was not moving. But when the little nozzle was
opened, it started to zip around the room. So its speed changed.
And, as it goes bloozing around the room, its direction keeps changing too.
There's a whole lot of acceleration going on, so we know the forces on it
are unbalanced.

What is produced by AC and DC generators?
chemical energy
mechanical energy
electrical energy
magnetic energy
Answer:
electrical energy
Explanation:
In an AC and DC generator, electrical energy is generated in such systems.
Both AC and DC generators are used to produce electrical energy in order to power homes and industrial tools.
Electrical energy is produced due to movement of electrons. In the generators, often times, a fuel is the source of the energy for the process. The fuel has a chemical energy which is converted to electrical energy through the design of the system.In a pressure cooker, a lid is screwed tightly onto a pot so that the air pressure in the pot is increased.

Which of the following is not apart of the Particle Theory of Matter? *
A. Atoms are always in motion
B. The motion of atoms increase with temperature
C. Atoms attract each other
D. Atoms do not have empty spaces between them
Answer:
D. Atoms do not have empty spaces between them
Explanation:
That atoms do not have empty spaces between them is not part of the particle theory of matter.
Here are some of the postulates of the theory;
A gas is composed of a large number of identical molecules moving at different speeds. The space occupied by gas molecules is negligible compared to the volume of space they occupy. The temperature of a gas is a function of their average kinetic energy.The distance versus time plot for a particular object shows a quadratic relationship.

A 15.0kg object is resting on the earth. What is the mass and weight of the object?
Answer:
The mass of the object is 15.0 kg
The weight of the object is 147.15 N
Explanation:
The mass of the object is the quantity of matter contained in the object or the measure of the its property of inertia.
The mass is constant through out the universe
The mass of the object is given as 15.0 kg
The weight of the object is the force of attraction of the Earth on the object
The weight is dependent on the interacting objects.
The weight of the object = The mass of the object × Acceleration due to gravity
Where;
The acceleration due to gravity, g = 9.81 m/s²
∴ The weight of the object = 15.0 kg × 9.81 m/s²= 147.15 N
The weight of the object = 147.15 N
