You paddle a conoe with a force of 156 n. you and the canoe have a combined mass of 220 kg. what is the acceleration of the canoe?
a. 1.4 m/s2
b. 1.1 m/s2
c. 2.3 m/s2
d. 0.7 m/s2

Acceleration of the canoe is 0.7 m/s².

Explanation:

It is given that,

Force acting on the conoe, F = 156 N

Combined mass of, m = 220 kg

We have to find the acceleration of the canoe. It can be calculated suing second law of motion. Mathematically, it is given by :

F = m a

a = 0.7 m/s²

So, the acceleration of the canoe is 0.7 m/s². Hence, the correct option is (d).

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
