Answer:
Both will turn red
Both will turn blue
X will turn red and Y will turn blue
X will turn blue and Y will turn red
Answer:
X will turn blue and y will turn red
Explanation:
Since X has a pH of 9, it will turn blue because anything with a pH higher than 7 turns blue. Since Y has a pH of 4, it will turn red because anything with a pH lower than 7 turns red.

Two identical spheres (of equal mass) a distance of 10 meters apart exert a force of gravity of 0.00050 N on each other. What are their masses?
Answer:
The gravitational force between two objects is written as:
F = G*m1*m2/r^2
Where:
G = 6.67*10^(-11) m^3/kg*s
m1 and m2 are the masses of the objects.
r is the distance between the objects.
In this case, we know that:
F = 0.0005 N
r = 10m
and because the two spheres are identical, we have that:
m1 = m2 = M
then we have the equation:
0.0005 N = (6.67*10^(-11) m^3/kg*s)*(M^2/(10m)^2)
0.0005 N*(10m)^2/(6.67*10^(-11) m^3/kg*s) = M^2
√( 0.0005 N*(10m)^2/(6.67*10^(-11) m^3/kg*s) ) = M = 27,379.3 kg
The mass of each sphere is 27,379.3 kg

Explanation:
Bicycle A with mass 40 Kg is traveling with a velocity of 4 m/s and Bicycle B with mass 20 Kg is traveling with a velocity of 2m/s. The two bicycles have kinetic energy
Calculate it and state which bicycle has higher energy and why?
Answer:
bicycle A has a greater K.E.
Explanation:
K.E = 1/2mv²
bicycle A = 1/2 × 40 × 4² = 320J
bicycle B = 1/2 × 20 × 2² = 100J
bicycle A has a greater K.E. because it has bigger mass and moves with faster velocity
3. What are the forces present on the rope?
Answer:
The pulling force that acts along a stretched flexible connector, such as a rope or cable, is called tension, T. When a rope supports the weight of an object that is at rest, the tension in the rope is equal to the weight of the object: T = mg.
Who could explain the phenomenom of interference of light?
Answer:
When the waves reflected from the inner and outer surface combine they will interfere with each other, removing or reinforcing some parts of white light by destructive or constructive interference. ... This results in color.
Explanation:
this is what we studied
so basically there is like a surface
and 2 different waves coming out of the same source
they will combine and start removing parts of the white light (which originally consists of 6 to 7 colors)
results in showing these colors
4. A car, initially traveling east with a speed of
5.0 m/s, is accelerated uniformly at 2.0 m/s2 east for
10 s along a straight line. During this 10 s
interval the car travels a total distance of
A. 50 m
B. 60 m
C. 100 m
✓ D. 150 m
Answer:
150 m
Explanation:
Given,
u=5m/s
a=2m/s2
t=10s
v=?
s=?
Now,
v=u+at
=5+2×10
=5+20
=25m/s
So,
s=u+v/2×t
=5+25/2×10
=30/2×10
=15×10
=150m
Put them in order to smallest to largest: centimeter, femtometer, kilometer, light year, meter, nanometer

Answer:
Strong Positive Linear Line Correlation
Explanation:
According to the diagram, there is a strong positive linear line correlation between velocity and distance of galaxies. Hubble showed that galaxies are receding away from people with a velocity that is proportional to their distance from people more distant galaxies recede faster than nearby galaxies.
About the diagram: Velocity is the distance relation among extra-galactic nebulae. Radial velocities is corrected for solar motion, are plotted against distances estimated from involved stars and mean luminosities of nebulae in a cluster. The black discs and full line represent the solution for solar motion by using the nebulae individually; the circles and broken line represent the solution combining the nebulae into groups; the cross represents the mean velocity corresponding to the mean distance of 22 nebulae whose distances could not be estimated individually.
Why is it hard to respond with action at times?
what is the process of subduction
Answer:
Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle. Regions where this process occurs are known as subduction zones.
