the answer to this question is B relative humidity!
b. Mars and Jupiter.
c. Jupiter and Neptune.
d. Mars and Earth.
Answer:
b. Mars and Jupiter.
Explanation:
Asteroids are irregular sized and shaped rocky bodies -very small as compared to a planet which revolve around the sun in elliptical orbit. In the solar system, majority of the asteroids can be found in the asteroid belt which lies between the orbits of Mars and Jupiter. It is thought to be the debris of an unformed planet due to large gravity of Jupiter. Examples of asteroids - Ceres, Vesta, Eros etc.
The acceleration is
Explanation:
We can answer this question by using Newton's second law, which states that the net force acting on an object is equal to the product between the mass of the object and its acceleration:
where
F is the force
m is the mass
a is the acceleration
In this problem, we have
m = 25 kg is the mass of the rider+bicycle
F = 400 N is the force
Solving for a, we find the acceleration:

Answer:
5.0 x 10-5 T
Explanation:
Answer:
402m
Explanation:
We can solve this easily by using the free fall formula:
On both cases the final velocity will be 0m/s (maximum height), so we have:
We know that the velocity the person imparts to the ball will be the same either on Earth or on the Moon, so we write for both cases:
Which means
So we get (taking into account that gravity on earth is 6 times gravity on the Moon):

Answer:
mass
Explanation:
The density of a substance is defined as the ratio of mass of the substance to the volume of the substance.
It is a scalar quantity.
Its SI unit is kg/m^3.
By comparing the densities we get the idea about how dense the substance is.
For example, cotton and iron, the density of cotton is much less than iron so the cotton is less dense than iron.
The relative density is defined as the ratio of density of substance to the density of water at 4 degree C.
The density of water is maximum at 4 degree C.
Density is the mass per unit volume.
Density is a physical property of matter that describes the mass of a substance per unit volume. It is typically expressed in units like grams per cubic centimeter or kilograms per cubic meter. Density helps identify and compare substances, as objects with higher density are heavier for a given volume, while less dense substances are lighter.
Density is the mass per unit volume of a substance or object, defined as p = m/V. The SI unit of density is kg/m³. For many situations, grams per cubic centimeter (g/cm³) are used for the densities of solids and liquids, and grams per liter (g/L) are used for gases.
