Answer:
On the side of the Earth opposite from the sun
Explanation:
As our Moon continues its orbit counterclockwise around Earth (viewed from above the north pole), more and more of the illuminated part of the Moon becomes visible to us, until it reaches the “full Moon” stage. A full Moon occurs when the Moon has moved in its orbit so that Earth is “between” the Moon and the Sun.

Two particles A and B start simultaneously from a Point P with velocities 20 m/s and 30 m/s respectively. A and B move with acceleration equal in magnitude but opposite in direction. When A overtakes B at Q, its velocity is 30 m/s. The velocity of B at Q :
Answer:
20 m/s
Explanation:
Given
u(A) = 20 m/su(B) = 30 m/sacceleration equal in magnitude but opposite in directionSolving
Velocity of A at Q = 30 m/sFrom, P to Q, Δv(A) = 30 - 20 = +10 m/sTherefore, velocity of B at Q will be decreased by 10 as it is equal in magnitude but opposite in direction to AΔv(B) = v(B at Q) - u(B at P)-10 m/s = v(B at Q) - 30 m/sv(B at Q) = 30 - 10 = 20 m/sWhich would take more force to stop in 17. 3 seconds: a 3. 2 kg ball rolling in a straight line at a speed of 0. 3 m/sec or a 4. 1 kg ball rolling along the same path at a speed of 1. 2 m/sec?

What is the power of a toaster if it can perform 3500 j of work In 3 minutes
Answer:
Around 20 watts, or 19.4W exactly
Explanation:
to calculate the power in a time frame you use
Joules/Time(Seconds) = W (your power)
So, we take 3500 joules / 3min (180sec)
3500/180 = 19.4W, if your question asks you to round up/down, round up to 20W of power! good luck!
A uniform cube with mass 0.500 kg and volume 0.0270 m3 is sitting on the floor. A uniform sphere with radius 0.400 m and mass 0.800 kg sits on top of the cube. How far is the center of mass of the two-object system above the floor
Answer:
44 1/3 cm
Explanation:
The cube has an edge length of ∛0.027 m = 0.3 m, so a center of mass (CoM) 15 cm above the floor.
The sphere's center of mass is 40 cm above the top of the cube, so is 70 cm above the floor. The weighted average of the CoM locations is ...
((15 cm)(0.700 kg) +(70 cm)(0.800 kg))/(0.700 kg +0.800 kg)
= (10.5 kg·cm +56 kg·cm)/(1.500 kg) = 44.333... cm
The center of mass of the two-object system is 44 1/3 cm above the floor.

you want to make some hot chocolate with 1000.00 grams of h20. if it takes 435000 joules of energy to heat you water, what is the temperature change?
The temperature change from the calculation is obtained as 104 degrees.
What is energy?The term energy is described as the ability to do work. Now we are told that the energy that is added to the water is 435000 joules.
Given that;
H = mcdT
m = mass
c = specific heat capcity
dT = temperature change
dT = H/mc
dT = 435000/1000 * 10^-3 * 4200

A bowling ball with a mass of 9kg is thrown down a lane with a constant speed of 3 m/s. The ball hits the 1.5kg pin, initially at rest, at the end of the lane. After the collision the pin moves with a speed of 5 m/s. How fast is the ball moving after the impact?
Answer:
M1 V1 = M1 V2 + M2 V3 conservation of momentum
V2 = (M1 V1 - M2 V3) / M1 where V2 = speed of M1 after impact
V2 = (3 * 9 - 1.5 * 5) / 9 = (27 - 7.5) / 9 = 2.17 m/s
Note: All speeds are in the same direction and have the same sign

The conversion of ozone to diatomic oxygen is represented by the equation above. Based on the data in the table above, what is the approximate average bond enthalpy for the oxygen-to-oxygen bonds in ozone?.
The approximate average bond enthalpy for the oxygen-to-oxygen bonds in ozone is 300 kJ/mol. The ozone is composed of three oxygen atoms, and it's highly reactive.
What is ozone?Ozone is a light blue-colored gas, that is highly soluble in an inert, non-polar solvent.

The velocity of a free falling ball at different time intervals on unknown planet is shown in Figure 1.24.
Answer all of the following questions based on the image
A) What is the acceleration due to gravity of the planet?
B)What is the velocity at positions A and B?
C)What happens to the magnitude of velocity with passage of time? Why?
D)What factor(s) can influence the falling object on the Earth?
Answer:
a1 = (V2 - V1) / 1 s = 3.75 m/s^2
a2 = (V2 - V1) / (t2 - t1) = (7.5 - 3.75) / 1 s = 3.75 m/s^2
a3 = (V2 - V1) / (t2 - t1) = (7.5 - 3.75) / 1 s = 3.75 m/s^2
A) a = (a1 + a2 + a3) / 3 = 3.75 m/s^2
v = a (t2 - t1)
B) after 1 sec v = 3.75 m / sec^2 * 1 sec = 3.75 m/s
after 2 sec v = v0 + a t = 3.75 m/s + 3.75 m/s^2 * 1 s = 7.5 m/s
C) The velocity increases proportionaly to the time
D) One factor depends on the variation of the acceleration due to gravity because of different positions of measurement (on earth)
A much larger factor is due to air resisance of the air on the falling object
What is the purpose of the outer reflective fabric layer of a spacesuit?.
Explanation:
The purpose of the fabric is to deflect the harmful electromagnetic radiation from the sun and other sources. Higher energy radiation such as gamma rays or UV rays can ionize the atoms in our skin and organs. Therefore, it would be beneficial to deflect that radiation
Answer:
To cope with the extremes of temperature, most space suits are heavily insulated with layers of fabric (Neoprene, Gore-Tex, Dacron) and covered with reflective outer layers (Mylar or white fabric) to reflect sunlight.
