Answer: type of force is friction
Explanation:
Answer:
They have mass is always true.
Answer: The correct answer is Image B.
Explanation: For an object to accelerate, there should be unbalanced forces present. An object will move in the direction of net force.
Balanced forces are defined as the forces acting on the same object which are equal in magnitude but act in opposite direction. The net forces are 0.
Unbalanced forces are defined as the forces acting on the same object which are unequal in magnitude. The net force is non-zero.
For the given images:
Image A: This box will accelerate easily because the net force is non-zero and is moving in right direction.
Image B: This box will not accelerate because the net force is zero as all the forces are balancing one another. Hence, the object will stay at rest.
Image C: This box will accelerate easily because the net force is non-zero and is acting in between the normal and applied force.
Image D: This box will accelerate easily because the net force is non-zero and is moving in right direction.
Hence, the correct option is Image B.
Answer:
average speed = 18 miles / hour
Explanation:
Given data
drive = 396 miles
time = 8 am Tuesday to 5 pm Wednesday = 33 hours
lunch = 30 min Tuesday + 30 min Wednesday = 60 min = 1 hour
sleep = 7 pm Tuesday to 5 am Wednesday = 10 hours
to find out
average speed
solution
we know that he take total time = 33 hours and he took rest + luch = ( 1 + 10 hours)
so total travel time is = 33 - 11 = 22 hours
so
average speed = distance / time
average speed = 396 / 22
average speed = 18 miles / hour
Answer:
Luster: Metals are shiny when cut, scratched, or polished.
Malleability: Metals are strong but malleable, which means that they can be easily bent or shaped. ...
Conductivity: Metals are excellent conductors of electricity and heat.
