Answer:
A cell is the basic block of life and is always changing to fit its environment.
Explanation:
A cell is the basic founding block of a living organisms. In other words, a cell is the basic membrane unit which contains fundamental molecules of life. It is the cell that all living things are composed of.
The cell always changes with the surroundings and environment and it adapts to it. The cells requires a constant adjustments as the conditions inside and the outside the cells changes to keep a stable internal environment. Because the environment internally and externally is always changing, the cell continuously make adjustments to stay at or the near the set point.
Answer:
The acceleration due to gravity of that planet is, gₐ = 1.25 m/s²
Explanation:
Given that,
Mass of the planet, m = 1/2M
Radius of the planet, r = 2R
Where M and R is the mass and radius of the Earth respectively.
The acceleration due to gravity of Earth, g = 10 m/s²
The acceleration due to gravity of Earth is given by the relation,
g = GM/R²
Similarly, the acceleration due to gravity of that planet is
gₐ = Gm/r²
where G is the Universal gravitational constant
On substituting the values in the above equation
gₐ = G (1/2 M)/4 R²
= GM/8R²
= 1/8 ( 10 m/s²)
= 1.25 m/s²
Hence, the acceleration due to gravity of that planet is, gₐ = 1.25 m/s²
Answer:
951 Gaspra orbits the Sun near the inner edge of the main asteroid belt between Mars and Jupiter. Gaspra was named by its discoverer Neujmin for a resort on the Crimean peninsula. Consequently, many of the asteroid's craters have been named for resorts and spas worldwide.
Explanation:
Assuming no loss of x-direction velocity due to air resistance the bolt will be moving horizontally at 150m/s for 25s. Distance is speed x time so
D=(150)(25)=3750m
Diverging lens diverges ray of light. Their focal length is taken as negative because according to sign convention, the radius of curvature of that surface on which light refracts is to the left and every number to the left of 0 in real number line is taken as negative.
Pole is considered as origin. If focal point(F) lies to the left of pole, then it is taken as negative. Why? it is a rule
