False, because if you take too much calories, you are have too much. That means you are in the positive, you have too much energy.
and if you take fewer, you will have less calories, so less energy.
-ZERO- No 17.6 pound Earth-bound cat is going to be able to jump to the top of a 6 feet 7 inch bookshelf unassisted! Someone should call the SPCA on the writer of this textbook question ;-)
Assuming that this overweight cat is content being placed in such a lofty position, your professor probably wants the answer of <u>156.8 Joules</u>
Mass x Acceleration of Gravity (on Earth) x elevation = Potential Energy
8 Kg x 9.8 m/s2 x 2 m = 156.8 J
Answer:
the angular acceleration is 9.7 rad/
Explanation:
given information:
mass of thin rod, m = 3.2 kg
the length of the rod, L = 1.2
angle, θ = 38
to find the acceleration of the rod, we can use the torque's formula as below,
τ = Iα
where
τ = torque
I = inertia
σ = acceleration
moment inertia of this rod, I
I =
τ = F d, d =
cosθ
τ = m g
cosθ
now we can substitute the both equation,
τ = Iα
α = τ/I
= (m g
cosθ)/(
)
= 3gcosθ/2L
= 3 (9.8)cos 38°/(2 x 1.2)
= 9.7 rad/
hope it helps:)
Explanation:
A galvanometer is converted into an ammeter by connecting a low resistance in parallel with the galvanometer. This low resistance is called shunt resistance S. The scale is now calibrated in ampere and the range of ammeter depends on the values of the shunt resistance.
