To understand the distinction between mass and weight and to be able to calculate the weight of an object from its mass and Newt

Firdavs [7]

Answer: A.E.

Explanation: To understand the distinction between mass and weight and to be able to calculate the weight of an object from its mass and Newton's law of gravitation. The concepts of mass and weight are often confused. In fact, in everyday conversations, the word "weight" often replaces "mass," as in "My weight is seventy-five kilograms"

discuss the difference between molarity and molality, state the units of each, state the symbol of each, and give an example of

Afina-wow [57]

Molarity and molality both describe the concentration of a substance in terms of moles.
Molarity describes the number of moles of a substance per unit of volume, typically per liter (mol/l).
Molality describes the number of moles per unit of mass, typically kilograms (mol/kg).
When determining the molality of a solution, mol/kg can be obtained by finding the number of moles in the substance, and dividing that number by the the total weight in kilograms of that substance.
When determining the molarity of a solution, mol/l can be obtained by dividing the number of moles in a substance by the total volume in liters of that substance.

Onur drops a basketball from a height of 10m on Mars, where the acceleration due to gravity has a magnitude of 3.7m/s2. We want

lbvjy [14]

Explanation:

It is given that, Onur drops a basketball from a height of 10 m on Mars, where the acceleration due to gravity has a magnitude of 3.7 m/s².

The second equation of kinematics gives the relationship between the height reached and time taken by it.

Here, the ball is droped under the action of gravity. The value of acceleration due to gravity on Mars is positive.

We want to know how many seconds the basketball is in the air before it hits the ground. So, the formula is :

$\Delta x=v_ot+\dfrac{1}{2}at^2$

t is time taken by the ball to hit the ground

$v_o$ is initial speed of the ball

So, the correct option is (A).

Dinosaurs’ skeletons can be distinguished from those of other reptiles by the structure of the hips and legs.

jeyben [28]

True, they had a hole in their hip socket that allowed them to run faster than other reptiles of their size at the time. As well as most reptiles besides reptiles had legs to the side, rather than under them like dinosaurs did.

Hope this helps!

A circus tightrope walker weighing 800 N is standing in the middle of a 15 meter long cable stretched between two posts. The cab

Lorico [155]

Answer:

T = 10010 N

Explanation:

To solve this problem we must use the translational equilibrium relation, let's set a reference frame

X axis

Fₓ-Fₓ = 0

Fₓ = Fₓ

whereby the horizontal components of the tension in the cable cancel

Y Axis

$F_{y} + F_{y} - W =0$

2 $F_{y}$ = W

let's use trigonometry to find the angles

tan θ = y / x

θ = tan⁻¹ (0.30 / 0.50 L)

θ = tan⁻¹ (0.30 / 0.50 15)

θ = 2.29º

the components of stress are

F_{y} = T sin θ

we substitute

2 T sin θ = W

T = W / 2sin θ

T = $\frac{ 800}{ 2sin 2.29}$

T = 10010 N
