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.

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.
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

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.

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.
Answer:
B. The movement creates a difference in air pressure.
