Explanation:
because the acceleration is negative, this indicates a deceleration (or slowing down) . Hence we can say that:
The car is decelerating (slowing down), i.e its velocity is decreasing, at a constant rate of 5m/s².
Answer:
15.3 m/s
Explanation:
Radius of orbit= 6400+6300 = 12700 km
Circumference of orbit= 2*(22/7)*12700 =79796.45*10^3 m
Now,
Speed= Distance / Time
= 79796.45*10^3/(24*60*3600)
= 15.3 m/s
Answer:
202.95J
Explanation:
The formulae for the energy absorbed by the iron skillet is;
q=m*c*ΔФ where q=energy absorbed, m is mass of iron skillet, c is specific heat capacity and ΔФ is change in temperature
Given that;
m= 41g
ΔФ=20°-9°=11°
c=0.45 J/g°C
q= 41×0.45×11
q= 202.95 J
In a food pyramid, the organism that has the least amount of total energy available is the one that is in the bottom or last. In this case, given the list of organisms above, the organism that would have the least amount of total energy available would be the RED FOX. The answer is option A. Hope this answer helps.
