Answer: small cars can stop and go fast big trucks can not
Explanation:
Answer:
The apparent weight of the object is 0.465 N.
Explanation:
Given that,
Weight = 0.71 N
Water level = 50 mL
object inserted = 75 mL
We need to calculate the volume of solid
Using formula of volume
We need to calculate the buoyancy force
Using formula of buoyancy force
Put the value into the formula
We need to calculate the apparent weight of the object
Using formula of apparent weight
Put the value into the formula
Hence, The apparent weight of the object is 0.465 N.
Answer:
His machine must increase
Explanation:
The force (attractive if the charges are dissimilar, else repulsive) is along a line that connects the two particles.
Answer:
Average velocity, V = 2.5m/s
Explanation:
Given the following data
Displacement = 10m
Time = 4secs
Average velocity can be defined as the rate of change in displacement with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, average velocity is given by the equation;
Substituting into the above equation;
Average velocity, V = 2.5m/s
