Answer:
Wildfires
Explanation:
because wood is in the forst
Velocity of the bus = 75 miles/hr
Time taken by the bus to travel the distance between two cities = 2.5 hours
Let us assume the distance between the two cities = x
Then
Velocity = Distance/Time taken
Then Distance = Velocity * Time taken
= 75 * 2.5 miles
= 187.5 miles.
The distance between the two
cities is 187.5 miles.I hope this answer is what you were looking for. This
process is applicable for similar problems. In future you can always use this
method to determine the answer.
Yes, this is because particles in a solid there are more particles which are touching. They can only vibrate. But particles in a gas are far apart. This is the same for liquids to.
Answer:
a = 0.13m/s²
Explanation:
Given parameters:
Weight of horse trailer = 150kg
Distance covered = 250miles
Force applied on trailer = 20N
Unknown:
Acceleration of trailer = ?
Solution:
According to newton's second law of motion,"the acceleration of a body is directly proportional to the force on it and inversely proportional to the mass" .
Mathematically;
F = m x a
where f is the force
m is the mass
a is the acceleration
Input the parameters and solve;
20 = 150 x a
a = 0.13m/s²
