the answer is a unbalanced force is acting on the brick

viva [34]4 years ago

Answer:

B). An unbalanced force is acting on the brick.

Explanation:

Here as we can see the given figure there are two forces acting on the block

1. F_1 = 7,205 N Upwards

2. F_2 = 7,210 N Downwards

so here as we can see that force downwards is more in magnitude while upward force is less.

So here since downward force is more so the box will accelerate downwards and net force is given as

F_{net} = F_2 - F_1

F_{net} = 7210 - 7205 = 5 N

so here net force on this box is 5 N downwards and since there is unbalanced force on the box so box can not remains at rest.

An astronaut brings a cube from the earth to the moon. What is true about the inertial mass and weight of the cube?
Luden [163]

When an astronaut brings a cube from the Earth to the Moon, the inertial mass remains constant, but the weight decreases.

<h3>What is the difference between mass and weight?</h3>

Mass of the body is defined as the amount of matter a body have. It is denoted by m and its unit is kg.

Weight is defined as the amount of force an object expert on the surface. It is given as the product of mass and the gravitational pull.

When an astronaut brings a cube from the Earth to the Moon, the inertial mass remains constant, but the weight decreases.Because the value of the gravitational acceleration is different on the moon.

Hence, option D is correct.

To learn more about the mass, refer to the link;

A bus slams on its breaks and goes from 30 km/hr to 15km/hr in 4 seconds. What is its acceleration?
PolarNik [594]

Acceleration = (change in speed) / (time for the change).

Change in speed = (15 - 30) = -15 km/hr
Time for the change = 4 sec

Acceleration = (-15 km/hr) / (4 sec) = -3.75 km/hr per second .

Is that a lot ?  Not much ?

Let's convert it to a unit that we can think about:

     (-15 km/hr) x (1,000 m/km) x (1 hr / 3,600 sec) =

           (-15 x 1,000) / (3,600)  =  -(4 and 1/6) m/sec .

So the acceleration of the bus is    -(4 and 1/6) m/sec² .

The negative sign means that it slowed down.

(4 and 1/6) m/sec²  is about  42%  of the acceleration of gravity ...
the acceleration the bus would have if it drove off of a cliff.

When the car or the bus you're riding in slows down at that rate,
you feel  42%  of your weight pulling you forward against your
seat belt.  That's quite a drastic acceleration !
