Explanation:
the process by which heat or electricity is directly transmitted through the material of a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
Answer:
404.4 m
Explanation:
Converting the initial speed from km/h to m/s then
The acceleration is resolved as shown in the figure hence
deceleration of the truck along the inclined plane will be
where g is acceleration due to gravity
Substituting g with then
Using kinematic equation
and making s the subject then
where v and u are final and initial velocities respectively
Substituting 0 for v, 38.89 m/s for u and then
With the passage of time, the rock wall would be weathered under the impact of flowing water and would receede backwards.
Explanation:
Given details=
Water flowing at the pace of 2 to 3 feet per sec
It must be understood that flowing water act as an erosive agent here.
As the water flows, it carries with itself erosive tools which erode the rock surface. Since the speed of water is considerable, the erosion is quite significant. Due to the erosive action of the river, the rock wall would be continuously eroded starting from the tip and in turn, would recede backwards (in the upstream direction).
Answer:
Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9. So, how does this work? We can think of 5.6 x 10-9 as the product of two numbers: 5.6 (the digit term) and 10-9 (the exponential term).
Explanation:
Answer:
25 m/s
Explanation:
Centripetal acceleration is the square of the tangential velocity divided by the radius.
a = v² / r
15.625 m/s² = v² / (40 m)
v² = 625 m²/s²
v = 25 m/s
The speed of the car is 25 m/s.
