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:
kJ
Explanation:
= mass of 1 mole of water = 18 g
= given mass of water = 50 g
Number of moles of water in the given amount is given as
= Heat of fusion of water = 6.01 kJ/mol = 6010 J/mol
= specific heat of water = 75.3 J/mol
= Change in temperature = 22.0 °C
Amount of heat required is given as
J
kJ
Answer:
They have the same current.
Explanation:
According to the Ohm's Law, resistors in series have the same current, distinct potential differences and resistances. The case for n resistors in series are:
Atomic mass = number of protons + number of neutrons = 4+5 = 9 amu
