Answer:
The best description of inertia is an objects velocity
Although hand specimen identification is some what of an art; igneous rocks are classified using two critiria:
•Texture
•Chemical and mineral composition
Most of the time the rock name, such as basalt or granite, reflects the chemical composition. The minerals and textures are used as adjectives that modify the rock name. You might see a name like an olivine basalt or a quartz porphyry rhyolite.
Answer:
Explanation:
let A represent me and B represent my friend
A speed
=30 m/hr toward west
B speed
=40 m/hr toward south
after 1/2 hr
total distance cover by A =1/2 * 30 miles = 15 miles
total distance by B = 1/2*40 miles = 20 miles
now from figure
Differentiate above equation
Answer:
F=507.7N
Explanation:
According to Newton's second law:
in this case, the football players need to drag the coach at a constant velocity, thus means with no acceleration, so:
there are 20 degrees between the two ropes that means each player exerts a force 10 degrees from the zero reference.
Answer:
None.
Explanation:
- By definition, work is a process that it happens when an applied force
causes an object to change its position, i.e. to have a displacement.
Since the laptop cart is at rest while he stops at the water fountain, no
net work done is on the laptop cart.
