The mass of her friend is 28.57.

Force is a push or pulls upon an item because of the object's interaction with some other object. pressure is a power that can exchange the motion of an object. A force can reason an object with mass to alternate its speed, i.e., to boost up. pressure also can be described intuitively as a push or a pull. A force has each significance and course, making it a vector amount.

Calculation:-

given;

mass = ?

acceleration = 2.1 m/s

force = 60 N

Force = mass × acceleration

mass = force/acceleration

= 60 /2.1

= 28.57 kg

The phrase 'Force' has a unique meaning. At this degree, it is absolutely appropriate to describe a force as a push or a pull. A force is not something that an object consists of or 'has in it. A force is exerted on one object through another. The concept of a force isn't always restricted to living matters or non-living matters.

A 10 kg box hangs from a rope. What is the tension in the rope (in Newtons) if the box is stationary

Archy [21]

Answer:

T = 98 N

Explanation:

The gravity of the earth is known to be 9.8 m/s²

Data:

m = 10 kg
g = 9.8 m/s²
T = ?

Use formula:

$\boxed{\bold{T=m*g}}$

Replace and solve:

$\boxed{\bold{T=10\ kg*9.8\frac{m}{s^{2}}}}$

$\boxed{\boxed{\bold{T=98\ N}}}$

The tension in the rope is 98 Newtons.

Greetings.

A rock of mass m = 0.0450 kg is attached to one end of a string and is whirled around in a horizontal circle. If the radius of t

AleksAgata [21]

Answer:

Tension, T = 0.1429 N

Explanation:

Given that,

Mass of the rock, m = 0.0450 kg

Radius of the circle, r = 0.580 m

Angular speed, $\omega=2.34\ rad/s$

The tension in the string is balanced by the centripetal force acting on it. It is given by :

$T=\dfrac{mv^2}{r}$

Since, $v=r\omega$

$T=\dfrac{m(r\omega)^2}{r}$

$T=\dfrac{0.0450\times (0.580\times 2.34)^2}{0.580}$

T = 0.1429 N

So, the tension in the string is 0.1429 N. Hence, this is the required solution.

How does the size of a planet affected the amount and type of gas in its atmosphere

dalvyx [7]

There are lots of variables that directly and indirectly contribute to the presence of gas on a surface
if the size of a planet is relatively small it will in turn be that of a smaller area which results in the less area to be covered for gas which basically means higher presence
I can go in depth more but I don't think that would be necessary all you need to know is this ...based on the size and gas will in turn be parallel to it's conformity
