Answer: For 18 the inch is longer im not sure by how much, for 19 the the kilogram is 2.2 times heavier than a pound, QUART IS A LITTLE LESS THAN A LITER. ... An easy way to figure from liters to gallons, for example, is that a quart is a little less than a liter and 4 liters is a little more than 1 gallon. To be exact, 1 liter is 0.264 gallon (a little more than a quart), and 4 liters is 1.06 gallons,  30°C or 30°F? Correct answer: the table shows that 30°C is about 86°F, which is warmer than 30°F.   And sorry Im not sure how to do the rest

Suppose you first walk 12.0 m in a direction 200 west of north and then 20.0 m in a direction 40.00 south of west. How far are y
Tpy6a [65]

Complete Question

The  complete question is shown on the first uploaded image

Answer:

the compass direction of the resultant displacement is  \theta  =4.7^o south of west

Explanation:

Generally using cosine we can obtain the resultant R as follows

     R^2  =  A^2  + B^2 -2ABcos(70)

=>   R  =  \sqrt{12^2  + 20^2  - 2(12 ) *  (20) cos  70}

=>    R  =  19.48 \  m

We can obtain the direction of the resultant by first  using sine rule to obtain angle C as follows

       \frac{A}{sin  C}  =  \frac{R}{sin70 }

=>    C=  sin ^{-1} [\frac{A *  (sin 70)}{R} ]

=>    C =  sin ^{-1} [\frac{20 *  (sin 70)}{19.48} ]

=>  C =  74.7 ^o

Then the direction is obtained as

       \theta  =  C  -  70

=>    \theta  = 74.7   -  70

=>     \theta  =4.7^o

Hence the compass direction of the resultant displacement is  \theta  =4.7^o south of west

How much work is needed to lift a barbell that has a weight of 445 N a total of 2 meters off ground
AleksAgata [21]

Answer:

Total work done to lift barbell = 890 J

Explanation:

Given:

Weight of barbell (F) = 445 N

Height (Distance) = 2 meter

Find:

Total work done to lift barbell = ?

Computation:

⇒ Work = Force(F) × Distance

⇒ Total work done to lift barbell = Weight of barbell × Distance

⇒ Total work done to lift barbell = 445 N × 2 meter

⇒ Total work done to lift barbell = 890 J
