Which action might lead scientists to develop new explanations about the universe?
Answers
Answer:
Designing experiments to replicate the conditions in which life may have first evolved on Earth
Explanation:
In 1953, Stanley L. Miller and Harold C. Urey conducted an experiment to prove that life started from inanimate objects. The research was conducted by utilizing proposed chemical substances, mixed together through a scientific design process. The outcome of the research is the predicted atmospheric conditions before the pre-living form started on earth.
Therefore, in this case, the action that might lead scientists to develop new explanations about the universe is "Designing experiments to replicate the conditions in which life may have first evolved on Earth."
why a magnetic compass is used to determine direction
Answers
Answer:
compass is an instrument used for navigation and orientation that shows direction relative to the geographic cardinal directions (or points). Usually, a diagram called a compass rose shows the directions north, south, east, and west on the compass face as abbreviated initials.
This works because the Earth itself has a magnetic field which is similar to that of a bar magnet. The compass needle aligns with the Earth's magnetic field direction and points north-south.

A coin is dropped from the top of the Tower of Pisa, 53m above the ground. What is the coin's initial velocity?
Answers
Answer:
Initial velocity U = 0
Final velocity V = 32.23 m/s
Explanation:
Given that a coin is dropped from the top of the Tower of Pisa, 53m above the ground.
What is the coin's initial velocity ?
Since the coin is dropped from the tower, the initial velocity U will be equal to zero.
Therefore, U = 0
But the final velocity V will be calculated by using the formula
V^2 = U^2 + 2gH
V^2 = 0 + 2 × 9.8 × 53
V^2 = 1038.8
V = sqrt ( 1038.8)
V = 32.23 m/s

A proton and a neutron are each close to a positive nucleus.
How does the charge on the nucleus affect the proton and the neutron, if at all?
A The neutron is attracted; the proton is repelled.
B The neutron is not affected; the proton is repelled.
C The proton is attracted; the neutron is repelled.
D The proton is not affected; the neutron is repelled.
Answers
Answer: b
Explanation:Because protons are positive and the nucleus is positive so it will be repelled and the neutron is neutral so it will be unaffected.
A ball, initially at rest, reaches a speed of 20 m/s at the bottom of the apparatus. If it takes the ball 10 seconds to reach the bottom, what is the ball’s average acceleration?
Answers
Answer:
2 m/s²
Explanation:
Given:
v₀ = 0 m/s
v = 20 m/s
t = 10 s
Find: a
a = (v − v₀) / t
a = (20 m/s − 0 m/s) / 10 s
a = 2 m/s²

you throw a basketball straight up into the air with a speed of 24.5m/s. how long does it take to reach its highest point
Answers
Answer:
2.5 seconds.
Explanation:
Time equals speed divided by acceleration. gravitational acceleration is equal to 9.8 [tex]\frac{m}{s^{2} }[/tex]. You know that the speed is equal to 24.5 m/s, so plug those values into the equation.
24.5 / 9.8 = 2.5 seconds.
Hope this helps!
Answer: 2.5 s
Time=speed/acceleration
Gravitational Acceleration=9.8 m/s^2
Speed=24.5 m/s
Time=24.5/9.8=2.5 s

function of alcohol in alcohol thermometer
Answers
Alcohol is increasingly expanding with heat. Having it go up the ladder quicker than a lot of liquids would have done. It has a low freezing point, too. It's easy to dye because of the readability. I 'm sure someone will teach you about the evaporative effects of alcohol, and why they do these things. Though that's why it's used briefly in thermometers.
Answer:
Fahrenheit's first thermometer contained alcohol, which has a lower freezing point than water. ... Glass bulb thermometers work because liquids, such as water, alcohol, or mercury, expand slightly when the temperature rises. If the liquid is trapped in a narrow tube, it has nowhere to go but up. I think this may help you
How long does it take an object to accelerate from 12 m/s to the right to 32 m/s to
the right with an acceleration of 5 m/s2 to the right?
Answers
Answer:
4 seconds
Explanation:
Given:
v₀ = 12 m/s
v = 32 m/s
a = 5 m/s²
Find: t
v = at + v₀
32 m/s = (5 m/s²) t + 12 m/s
t = 4 s
17. The weight of an object on a given planet can be found by using the formula W = mg, where W is the weight of the object measured in newtons, m is the mass of the object measured in kilograms, and g is the acceleration due to gravity on the planet measured in meters per second squared. An object on Earth has a weight of 150 newtons. If the acceleration on earth is 9.8 m/sec?, on Mercury it is 3.6, on Saturn it is 11.1 and on Jupiter it is 26, on which planet would the same object have an approximate weight of 170 newtons?
Answers
Answer:
Saturn
Explanation:
W = mg
150 N = m (9.8 m/s²)
m = 15.3 kg
W = mg
170 N = (15.3 kg) g
g = 11.1 m/s²
The planet is Saturn.
A bird flies 6km east, then 4km west. Find the total distance traveled and displacement (d) after this flight.
Answers
Given :
A bird flies 6 km east, then 4 km west.
To Find :
the total distance traveled and displacement after this flight.
Solution :
a)
We know , total distance is the amount of how much ground an object has covered .
Distance = 6+4 km = 10 km .
b )
Displacement is the shortest distance from one point to another .
Now , here the object first move 6 km east then moves 4 km west .
So , his distance from the starting position is :
Displacement = 6 - 4 km = 2 km .
Hence , this is the required solution .
