Helen [10]
The product of √30 and √610 is 10√183.


√30  = √(2×3×5)
and √610 = √(2×5×61

Since 61 can't be factorised further.
Therefore, the value of √30×√610 is
= √(2×3×5×2×5×61)
= 2×5×√(3×61)
=10√183

A forklift does 450 J of work to lift a 150 N hot tub. How high is the hot tub lifted? Round your answer to the nearest whole nu
vivado [14]
There are already 2 givens, hence we can do direct substitution to get the answer. To make the process simpler, derive the distance formula from the Work formula.

Work = Force x Distance

Distance = \frac{Work}{Force}


Work is 450J while the force is 150N hot tub

To get the proper units, get the equivalent of Joule to eliminate newton. A joule Is equal to 1 N-m

Distance = \frac{450N-m}{150N}
Distance = 3m

Hence, the hot tub is lifted 3 meters.

An object of mass 300 kg is observed to accelerate at the rate of 4 m/s 2 . Calculate the force required to produce this acceler
Marianna [84]

Answer:

F = 1200 N

General Formulas and Concepts:

<u>Forces</u>

Newton's Second Law of Motion: F = ma

  • F is force (in N)
  • m is mass (in kg)
  • a is acceleration (in m/s²)

Explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

<em>m</em> = 300 kg

<em>a</em> = 4 m/s²

<u>Step 2: Find Force</u>

  1. Substitute in variables [Newton's Second Law of Motion]:                           F = (300 kg)(4 m/s²)
  2. Multiply:                                                                                                            F = 1200 N
