Answer:
t = 3.0s
Explanation:
U = 2.0m/s , V = 0 (stop) , S = 3m , t =?
From V^2 - U^2 = 2aS
=) a = -4/6 = -0.667m/s^2
Now again by V-U = at
We have t = -U/a = 2/0.667 = 3s
Required time is t = 3.0s
Answer:
Kinetic - a box moving
Thermal - sand that feels warm
Electrical - lightning
Radiant - radio waves
Gravitational Potential - fruit hanging from a tree
Solution: C. Pangea
The hypothesis of Continental drift suggests that in past, there was only one landmass on the Earth -Pangaea which drifted apart due to movement of plate tectonics causing earthquake. This hypothesis is supported by many evidences which includes presence of similar fossils on different landmasses, common land features such as widespread presence of glacial sediments etc.
HYDROGEN GAS + OXYGEN GAS= HYDROGEN PEROXIDE H2+O2=H2O2 HYDROGEN PEROXIDE IS A LIQUID BECAUSE HYDROGEN PEROXIDE CAN NEVER BE A SOLID BECAUSE TWO LIQUIDS CAN NEVER FORM A GAS IT IS IMPOSSIBLE NO MATTER THE CONDITION
Answer:
1 mm^3 = 1.0 x 10^-9 m³
Hence;
5.23 x 10^-6 kg/mm^-3 = (5.23 x 10^-6 kg)/ 1x10^-9 m³
= 5230 kg/m³
