The boom of a fire truck raises a fireman (and his equipment – total weight 280 lbs) 60 ft into the air to fight a building fire
Simora [160]

Explanation:

Given that,

Weight = 280 lbs

Height = 60 ft

Power = 3.50 hp

(a). We need to calculate the work done by the boom on the fireman

Using formula of work done

Work\ done =Weight\ \times height

W'=W\times h

Put the value into the formula

W'=280\times60

W'= 16800 ftlbf

W'=\dfrac{16800}{778.169}

W'=21.59\ Btu

The work done by the boom is 21.59 Btu.

(b). We know that,

1 hp = 550 ft lbf

So, P = 3.50\times550

P=1925\ ft-lbf/s

We need to calculate the time

Using formula of time

t = \dfrac{W}{P}

Put the value into the formula

t=\dfrac{16800}{1925}

t =8.7\ sec

The time is 8.7 sec.

Hence, This is the required solution.

A student made the following observations about a squirrel’s movements:
dalvyx [7]

The correct option is <u>D</u>.

Qualitative observations are observations that are made using our senses of sight, hearing, smell, taste and feel. These observations do not involve numbers or measurements of any kind.

The student's observations regarding the squirrel as is mentioned in options A, B and C involve measurements. Therefore these are not qualitative observations.

Option D, however, is made on the basis of sight, where the student observes the squirrel moving in a zigzag manner.

Therefore, of all the three observations, the student's observation that the squirrel ran in a zigzag pattern is the qualitative observation.
