A stone is thrown horizontally at 8.0 m/s from a cliff 78.4 m high. How far from the base of the cliff does the stone strike the ground?
Answers
A stone is thrown horizontally at 8.0 m/s from a cliff 78.4 m high. The distance from the base of the cliff does the stone strike the ground is 64 m.
What is distance?
Distance is defined as the entire path traveled by an object in motion, regardless of journey direction. Three sight distances are primarily taken into account in the geometric design of road construction. Things that can be measured in terms of length include the dimensions of a section or a room. Distance is the separation between two things, like two cities or two points. There will never be a negative value for either length or distance.
A projectile is an object that is launched vertically into the air and moves while being pulled by gravity. A horizontally launched object that defies gravity is referred to as a projectile.
Thus, a stone is thrown horizontally at 8.0 m/s from a cliff 78.4 m high. The distance from the base of the cliff does the stone strike the ground is 64 m.

Answer: oscillating universe theory
Explanation:
- The oscillating universe theory is a modification of the famous big bang theory.
- According to this theory, there are successive cycles of expansion and contraction that occurs in the universe and due to the contraction, the universe gets confined into a very small volume which has a large density.
- When the universe gets confined in such a way then, it is said that a 'bounce' will occur and, it would thus oscillate between the big bang and the big crunch.
- Thus, this theory states that for every big bang there is a big crunch.
Final answer:
The Oscillating Universe Theory suggests that for every big bang there is a big crunch, imagining the universe as undergoing endless cycles of expansion and contraction.
Explanation:
The theory that suggests that for every big bang, there is a big crunch is known as the oscillating universe theory. This theory proposes that the universe undergoes endless cycles of expansion (Big Bang) and contraction (Big Crunch). It's like a ongoing cosmic heartbeat, where our universe alternatively expands and contracts.
The other three theories mentioned, the inflation theory, the steady state theory, and the big bang theory, each have their own illustrations of the universe's formation. None of them, however, necessarily involve the concept of a big crunch following a big bang.

Boiling the water away, leaving the substance behind in the beaker is the way to separate the mixture. The correct option is A.
What is a mixture?
A mixture is basically a substances comprised of two or many distinct chemical substances which are indeed not linked covalently.
A mixture is the usually physicalcombination of two or more substances that retain their identities as well as are mixed in the way to form solutions, suspensions, along with colloids.
When two or more distinct substances are physically combined, a mixture is formed that can be distinguished back into its original substances.
When two or more substances combine to form a new substance that cannot be separated back into its original substances, a chemical reaction occurs.
The mixture can be separated by boiling the water away and leaving the substance in the beaker.
Thus, the correct option is A.

b. The current will decrease
c. The voltage through each bulb will
Explanation:
a. For a series of resistors, the equivalent resistance is given by
so, we see that adding more resistors in series, will increase the total resistance.
b. In a series circuit, the current through each bulb is the same for each bulb, and it is equal to the current flowing in the circuit, which is given by Ohm's law
where V is the voltage supplied by the battery and R the total resistance of the circuit. Since the voltage provided by the battery, V, does not change, while the total resistance R increases, the current I will increase.
c. The voltage through each bulb is given by
where R_i is the resistance of the individual resistor and I is the current. Since the value of R_i does not change, while I (the current) has decreased, the voltage available to each bulb, V, will decrease.
