A block of lead has dimensions of 4.50cm by 5.20cm by 6.00cm. The block weighs 1587g. From this information, calculate the density of the lead.
Answers
Volume = Area x Length = (4.50 x 5.20) x 6.00 = 140.4
Density = 1587 x 140.4 = 222,814.8 g/cm3 (cubed)
222,814.8 / 1000 = 222.8148 kg/m3 (cubed)

Two billiard balls move toward each other on a table. The mass of the number three ball, m1, is 5 g with a velocity of 3 m/s. The mass of the eight ball, m2, is 6 g with a velocity of 1 m/s. After the balls collide, they bounce off each other. The number three ball moves off with a velocity of 5 m/s. What is the final velocity and direction of the eight ball? +8.6 m/s +5.7 m/s –5.7 m/s –8.6 m/s.?

fulcrum to get the correct mechanical advantage?
Answers
Answer:
The distance of load from fulcrum is 5 m.
Explanation:
Given:
Mechanical advantage, MA = 0.4
Distance of force from fulcrum is,
Distance of load from fulcrum is,
We know that, Mechanical advantage of a machine is the ratio of the effort arm and load arm.
So, Mechanical advantage is given as:
Therefore, the distance of load from fulcrum is 5 m.

Explanation:
Most of the air's moisture evaporates from rivers, lakes, seas, and oceans. Water at the surface of the Earth evaporates into water vapor, which rises into the sky and forms clouds, which eventually release water back onto Earth as precipitation.

To complete the marathon of 26 miles in 4.5 hours, the average speed required is 9.3 kilometers per hour.
What is average speed?
To find the average speed required to complete a marathon of 26 miles in 4.5 hours, we can use the formula:
average speed = total distance / total time
The total distance of the marathon is 26 miles, which is equivalent to 41.84 kilometers (1 mile is approximately 1.60934 kilometers).
The total time we want to complete the marathon in is 4.5 hours, which is equivalent to 4.5 × 60 = 270 minutes.
Converting the units of distance and time to kilometers and minutes respectively, we have:
average speed = 41.84 km / 270 min
Simplifying this expression, we get:
average speed = 0.155 km/min
To convert the units to kilometers per hour, we can multiply by 60, since there are 60 minutes in an hour:
average speed = 0.155 km/min × 60 min/h = 9.3 km/h

Jenny's acceleration was negative during the intervals of time when her speed was decreasing.
That's really all we can tell, because you really haven't given us any information except her name.
Final answer:
Negative acceleration refers to times when Jenny was slowing down in her motion. Exact intervals cannot be given without further information on her motion timeline or graphical representation.
Explanation:
The periods during which Jenny was negatively accelerating would be the time intervals during her motion when her speed was decreasing. In a physics context, negative acceleration (or deceleration) means that the object (in this case, Jenny) is slowing down. For instance, if Jenny was running and began to slow down, the period from when she began slowing to when she stopped would be an interval of negative acceleration. However, without specific timelines or a graphical description of Jenny's motion, it's impossible to determine the exact intervals of negative acceleration.
