1.Is molar mass always done for one mol of substance? Let me make up an example: 2H2(g)+O2(g)--> 2H2O When finding molar mas of water would it be 2(2(1.01)+2(16)) or just 2(1.01)+16? 2. I'm not really sure about endergonic exergonic reaction because my te...

A truck travels beneath an airplane that is moving 120 km/h at an angle of 24◦ to the ground. How fast must the truck travel to stay beneath the airplane? Answer in units of km/h What is the magnitude of the vertical component of the velocity of the plane...

A ball of mass 0.4 kg, initially at rest, is kicked directly toward a fence from a point 20 m away, as shown below. The velocity of the ball as it leaves the kicker’s foot is 16 m/s at angle of 46◦ above the horizontal. The top of the fence is 4 m high. T...

A 2.97 kg block initially at rest is pulled to the right along a horizontal surface by a constant, horizontal force of 12.9 N. The coeﬃcient of kinetic friction is 0.126. The acceleration of gravity is 9.8 m/s^2. Find the speed of the block after it has m...

A meter stick is supported at its center. If a load of 150 dynes is placed at the 20 cm mark, where should a 100 dynes load be placed in order that the stick remains in the horizontal position?

A 500 g metal ball is whirled in a vertical circle. What is the centripetal force which draws it toward the center of the circle as it passes through the highest point?

an airplane flying due north with a speed relative to the ground of 300 km/hr. it then encounters a cross-wind that is directed due east. of the resultant speed of the airplane is now 302 km/hr, how fast is the cross wind?

A DJ charges $250 for 1 hour of work and charges $410 for 3 hours of work. Write an equation that models this situation. Let "x" represent the number of hours worked and "y" represent the cost to hire the DJ. Thank you for the help! I appreciate it.

Animals convert co2 from the atmosphere into carbohydrates. Is this false?

True or false, do animals convert co2 from the atmosphere into carbohydrates?

block A has a mass of 20kg and block B has a mass of 10kg. What is the value of static friction would stop the block from sliding?

2x+3>0 so x>=-3/2 if it was less than -3/2 the inside of the squareroot would be negative and that number does not exist in real number system. For range If I remember it is normally y>0 for this function but since it is shifted up 3 it would now be y>=3

then how would you find vertical velocity component?

integrate statistics with "real-life" issues, such as day care, in order to interpret them.

Apparently the answer is 5.3 at 26 degrees but I don't understand why?

I meant to say help instead of fall. Oops!

*instead of galp. I hate autocorrect.

Thank you so much, Steve!

Okay...so then is it true?

So, Ms. Sue, would it be false?

you could add up 8,8,8,9,13,14 and that would be 60 so the answer i got was 60

The man pushes with a force of 200 N. The child and sled combo has a mass of 30 kg and the coefficient of static friction is 0.15. Find the friction force

Given the figure shown below, block A has a mass of 10kg and block B has a mass of 25kg. Assume the coefficient of friction between the blocks is four times the coefficient of friction between the block and the plane. Determine the normal force between bl...
