It is B

When we look at a red apple, it's absorbing colors from the sunlight. It absorbs all the colors of the rainbow—except for red. The red light reflects off the apple and our brain and eyes work together to let us know what color we are seeing.

A 52 kg child on a swing is travelling at 6 m/s . What is his gravitational potential energy if he has 1000 J of the mechanical

DiKsa [7]

Answer:

The correct answer is "64 J".

Explanation:

The given values are:

Mass,

m = 52 kg

Velocity,

v = 6 m/s

Mechanical energy,

= 1000 J

Now,

The gravitational potential energy will be:

⇒ $P.E=1000-\frac{1}{2}mv^2$

$=1000-\frac{1}{2}\times 52\times (6)^2$

$=1000-26\times 36$

$=1000-936$

$=64 \ J$

The carbon monoxide molecule (CO) consists of a carbon atom and an oxygen atom separated by a distance of

valkas [14]

Answer:

6.46*10^-11m

Explanation:

We can use the equation of the center of the mass of two atoms

$Xcm=\frac{mcxc+moxo}{mc+mo}$

If we take the origin at the center of the molecule carbon monoxice, xc will be 0, so

$Xcm=\frac{moxo}{mc+mo}$ = $\frac{xo}{mc/mo+1}$

$Xcm=\frac{1.13.10^-3}{0.750mo/mo+1}$ =6.46*10^-11m

Answer:

Buoyant Force: Cause and Calculation

The result is a net upward force (a buoyant force) on any object in any fluid. If the buoyant force is greater than the object's weight, the object will rise to the surface and float. If the buoyant force is less than the object's weight, the object will sink.

A car is traveling north at 17.7m/s After 12 s its velocity is 14.1m/s in the same direction. Find the magnitude and direction o

dem82 [27]

Answer:

Option B

0.3 m/s2 South

Explanation:

Acceleration, $a=\frac {v-u}{t}$ where v and u are final and initial velocities respectively, t is the time taken

Substituting 14.1 m/s for v, 17.7 m/s for u and 12 s for t then

$a=\frac {14.1 m/s- 17.7 m/s}{12}=-0.3 m/s^{2}$

Since this is negative acceleration, it's direction is opposite hence 0.3 m/s2 South
