You have measured the force of a hammer hitting a nail by using a new sensor. The result is 60 million dynes is this reasonable

Yes, it is Reasonable.

Explanation:

The problem states that by using a new sensor, the result is 60 million dynes.

Converting the force into Newtons, by using the formula,

1 newton = 10⁵ dynes,

i. e, 1 million dynes = 10 newtons.

we get,

60 million dynes = 60 x 10 newtons = 600 newtons.

The result using a new sensor is reasonable because atmosphere exerts a force of about 10 newtons on us and 600 newtons is just 60 times of it.

Thus 600 N can be applied by the hammer on the nail and it is reasonable.
