Answer:
1.56 m/s
Explanation:
For East direction, the 6 blocks is equivalent to 6*100=600 m
For West direction, 8 blocks is equivalent to 8*100=800 m
Speed is given by s=d/t where s is speed, d is distance covered and t is time taken
Total distance is 600+800=1400m
Time taken is 15 mins, converted to seconds will be 15*60=900 s
Speed, s=1400/900=1.5555555555555 m/s rounded off as 1.56 m/s
Answer:
<em>x < 4</em>
Explanation:
<u>Inequalities</u>
The inequalities relate expressions using signs different from the equal sign, like "<" or "<" among others.
They can be treated as a normal equation but in case of directional relationals, care must be taken when multiplying or dividing by negative numbers.
The inequality given in the question is
3x - 4 > 4x - 8
Subtracting 3x in both sides
3x - 4 -3x > 4x - 8 -3x
Simplifying
-4 > x - 8
Adding 8
-4 + 8 > x - 8 + 8
Simplifying
4 > x
The solution comes by flipping both sides and the inequality sign
x < 4
Answer:
Faster particles bump into slower particles ( A )
Explanation:
Thermal conduction in a solid involves the microscopic collision of particles in the solid and this particles are made up of electrons, molecules and atoms. the collisions occur when faster particles collide with slower particles and this happens in a disorganized manner.
when cannot say for sure in what direction each of the particles is moving but there is surely collisions between particles which in turn results to transfer of kinetic and potential energies
Answer:
W = F * S = Newtons * Distance = Joules (definition)
Joules and KiloJoules are obviously methods of describing energy
F = M a = kg * m / s^2 definition of force
F * S = kg * m^2 / s^2 also describes work
Answer:
B.
Explanation:
I'm pretty sure the answer is B because animals at the top need a lot of energy, so to make up for loss of energy at the higher levels, those organisms at the top have to consume a lot more.
