Answer:
1st t=d/s
2nd s=d/t
5th d=st
are all of the variations I came up with
Explanation:
the original formula for speed is s=d/t
then, I created a ratio of s/1=d/t and cross multiplied to find d=st
then, I isolated the t in one side by dividing by s on both sides.
Answer:
S = d/t
Explanation:
The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.
A car moves at 45 kilometers per hour.
Which option describes if the given value is speed or velocity?
1 velocity, because there is no specific direction
2 speed, because there is no specific direction
3 velocity, because there is a mention of time
4 speed, because there is a mention of time
Answer:
4
Explanation:
4. speed, because there is a mention of time
Speed v/s Velocity:Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Velocity is speed with a direction. For example: The Dog runs at 9 km/h (kilometers per hour) is a speed. But saying he runs 9 km/h Westwards is a velocity.Thus, the correct option is 4 since no direction is given so it cannot be velocity.

A student is getting ready to go on a bike ride, but her bike’s back tire is flat! She connects a pump to the valve and adds air to the tire until it is fully inflated and ready to ride.
After the addition of air to the tire, the air pressure inside the tire is now __________ the air pressure outside the tire.

Which is a characteristic of an amorphous solid?
has a distinct melting point
becomes softer as temperature rises
particles arranged in a repeating pattern
made up of crystals
Answer:
4. Becomes softer as temperature rises
Explanation:
An amorphous solid is any noncrystalline solid in which the atoms and molecules are not organized in a definite lattice pattern. Such solids include glass, plastic, and gel. Solids and liquids are both forms of condensed matter; both are composed of atoms in close proximity to each other.

Drag each label to the correct location on the image.
Jessica is visiting a park with her mother. Jessica sits on a swing. Her mother pulls the swing to a height of 3 meters above the ground and lets it go. The image shows Jessica at three positions on the swing. Jessica‘s mass is 44 kilograms and the maximum velocity of the swing is 5 meters/second. What’s the energy she has at each position shown? Ignore friction and air resistance.

This chart lists four examples of two objects that are in contact.
A 3-column table with 4 rows. The first column has entries Example 1, Example 2, Example 3, Example 4. The second column labeled Object 1 has entries fire, a metal at 80 degrees Celsius, the cool ocean, a tool with a lot of thermal energy. The third column labeled Object 2 has entries air, a metal at 12 degrees Celsius, the warm air, a material with little thermal energy.
Which statement accurately describes the flow of heat in each example?
Heat will flow from Object 1 to Object 2 in examples 2 and 4, and heat will flow from Object 2 to Object 1 in examples 1 and 3.
Heat will flow from Object 1 to Object 2 in examples 1 and 3, and heat will flow from Object 2 to Object 1 in examples 2 and 4.
Heat will flow from Object 1 to Object 2 in Example 3, and heat will flow from Object 2 to Object 1 in examples 1, 2, and 4.
Heat will flow from Object 1 to Object 2 in examples 1, 2, and 4, and heat will flow from Object 2 to Object 1 in Example 3.

Ok this is what I think I think it's D because when two mangnets have a force upon one thing at the same time I don't think it would move
plz help describe the motion of tongs
Answer:
Movements of the tongue
The primary movement of the tongue is up and down with flattening and spreading. Lateral tongue movements are not observed during this pattern. Tongue movements are accompanied by up and down movement of the jaw for chewing and biting. This is a normal tongue pattern observed in early chewing.
Explanation:
Answer:
The primary movement of the tongue is up and down with flattening and spreading.

Ken wants to jump and have some fun too! Barbie loans Ken her bungee cord. Is this a good idea? Explain with evidence and reasoning. (barbie bungee jump lab)
Answer:To ensure a safe and thrilling jump you will determine the relationship between the jump height and the
number of rubber bands used to make the bungee cord. You must allow your Barbie doll to come as
close to the floor as possible without sustaining any injuries or fatalities.

A student made the table shown to list some contact and non-contact forces.
Examples of Forces
Contact Forces Non-Contact Forces
The force exerted by a stretched spring The force applied by Earth and sun on each other
The electrical force exerted by a positive charge on a negative charge Magnetic attraction between two magnets
Which statement best explains why the table is incorrect?
Spring force is a force acting at a distance.
Electrical force is not a contact force.
Gravitational force can act between planets and sun only when they are in contact.
Magnetic attraction is a contact force
Speed force acting at a distance

What happens when warm air rises? (5 points) (will give brain)
a
Global temperature decreases.
b
The movement creates a difference in air pressure.
c
Cool air rises with it.
d
It moves towards the poles.
Answer:
b)
movement creates a difference in air pressure.
as warm air rises up it creates a vaccum so due to that the pressure in that region decreases.

1st Law - Law of Inertia 2nd Law - Law of Force and Acceleration 3rd Law - Law of Action-Reaction An eagle soars through the air by pressing its wings downward. The air, in turn, propels the bird upward.
Answer:hen a bird flies, its wings push in a down- ward and a backward direction. This pushes air downward and backward. By Newton's third law, the air pushes back on the bird in the opposite directions—upward and forward. This force keeps a bird in the air and propels it forward.
