Answer:

Tension is also known as Force...

and Force is mass× acceleration.

so....1000×0.70=700N

Answer:

\Huge \boxed{\mathrm{700 \ N}}

Explanation:

Tension is the force exerted.

\sf Force \ (N) = mass \ (kg) \cdot acceleration \ (m/s^2)

F=1000 \cdot 0.70

F=700

The tension in the cable is 700 N.

A box sits on the back of a flatbed truck. If the coefficient of static friction between the box and the truck bed is μs = 0.400
slava [35]

Answer:

28,699m

Explanation:

The force to make the box move should be <u>μs.N=μs.m.g=m.</u><u>|</u><u>a</u><u>|</u>

then,

|a|=μs.g

Being

μs coefficient of static friction,

N the force made by the truck on the box caused by the gravity force,

m the mass,

g the acceleration of gravity

and a the acceleration of the truck.

x = v \times t  +  \frac{1}{2} \times a \times   {t}^{2}

as the truck is stopping, the acceleration is negative. then,

x = v \times t  -  \frac{1}{2} \times  |a| \times   {t}^{2}

|a|  = v  \div  t \\ t = v \div   |a|

x = v \times (v \div   |a| ) -  \frac{1}{2} \times  |a| \times   {(v \div   |a|)}^{2}

x = v \times (v \div  μs.g ) -  \frac{1}{2} \times  |a| \times   {(v \div   μs.g)}^{2}

x =   \frac{{v}^{2}}{μs \times g} -  \frac{1}{2} \times  \frac{{v}^{2}}{μs \times g} \\ x = \frac{1}{2} \times  \frac{{v}^{2}}{μs \times g} \\ x = 0.5 \times  \frac{{(15m/s) }^{2} }{0.4 \times 9.8m/ {s}^{2} }  = 28.699m

A spotlight on the ground shines on a wall 15 meters away. A man 1.8 meters tall walks away from the spotlight toward the buildi
Alex17521 [72]

Answer:

s=(15-x)m

Explanation:

Let the distance from spotlight to wall be 15m, and distance from the man to the building be x.

#Therefore the height of the shadow as a function of the above is s=(15-x )m

Hence, height of the shadow is expressed as s=(15-x)m

#See attached photo for illustration

There is more land in the Northern Hemisphere than in the Southern Hemisphere. How might this difference affect CO2, concentrati
alexira [117]

Oxygen is a product of photosynthesis, therefor lover levels of C02 would be in the area with more water due to more phtosynthetic processes happening converting it into oxygen.

hope this helps, please mark brainliest. :)

Two difference between thrust and upthrust .
velikii [3]

Upthrust is the upward force exerted by fluids on the surface of an object immersed in fluids. Thrust:- It is the force acting perpendicular to the surface. Upthrust:- It is the upward force exerted by the fluid on the surface of an object immersed in liquid.

I hope it's help you
