Calculate the work done by a 47N force pushing a pencil against a force of 23 N

stira [4]

I believe the answer would be 24N
Explanation: Because the forces are going against each other, in order to calculate the work done we need to subtract them. 47-23=24

how long does it take a car to accelerate from 3.4m/s to 20.9m/s if the average acceleration is 6.0m/s (squared).

Gre4nikov [31]

Average acceleration is the ratio of the change in velocity to the time it takes for that change to occur:

$a_{\mathrm{av}}=\dfrac{\Delta v}{\Delta t}$

We want to find $\Delta t$ :

$6.0\,\dfrac{\mathrm m}{\mathrm s^2}=\dfrac{20.9\,\frac{\mathrm m}{\mathrm s}-3.4\,\frac{\mathrm m}{\mathrm s}}{\Delta t}$

$\implies\Delta t=2.9\,\mathrm s$

Please answer B, C, E, and D

Natasha_Volkova [10]

B- the biosphere needs the hydrosphere (water) to survive. They drink the water.
C- the biosphere use the géosphère as land/ home.
D-The géosphère depends on the hydrosphere for water. Without the water, the géosphère would eventually turn dry and nothing will be able to grow
E- The animals in the hydrosphere need air to survive. The gills on sea animals are used to filter out the water from the oxygen and use the oxygen to breathe. As the fish opens its mouth, water runs over the gills, and blood in the capillaries picks up oxygen that's dissolved in the water.

Answer:

the weight of the rider is 493.53 N

Explanation:

Given the data in the question and as illustrated in the image below,

Tension T = 1900 N

the rider is moving at a constant speed so the net force in the horizontal direction will be 0

In the horizontal direction

F $_{sail$ cos( 30° ) = Tcos ( 17° )

F $_{sail$ = Tcos( 17° ) / cos( 30° )

F $_{sail$ = 1900cos( 17° ) / cos( 30° )

F $_{sail$ = 2098.07 N

Now, In the vertical direction,

F $_{sail$ sin( 30° ) = W + T sin( 17° )

W = F $_{sail$ sin( 30° ) - T sin( 17° )

W = 2098.07sin( 30° ) - 1900sin( 17° )

W = 1049.035 - 555.506

W = 493.53 N

Therefore, the weight of the rider is 493.53 N
