The property of water that contributes to its ability to stick to certain surfaces is called

Gekata [30.6K]

Answer: Adhesion

Explanation: Adhesion is the tendency of dissimilar particles or surfaces to cling to one another (cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another). The forces that cause adhesion and cohesion can be divided into several types. This allows Particles in things like water to stick to surfaces

a large bottle contains a number of medicinal tablets each having a mass of 250mg the mass of all the tablets is 0.5kg calculate

lys-0071 [83]

Considering the change of units and rule of three, the number of tablets in the bottle is 2,000.

First of all, you know that each medicinal tablet has a mass of 250 mg, while the mass of all tablets is 0.5 kg. You can see that the measurements are in different units of measurement, so you must make a change of units so that they are in the same units.

So, knowing that 1 kg is equal to 1,000,000 mg, you can apply the following rule of three: if 1 kg is equal to 1,000,000 mg, 0.5 kg is equal to how many mg?

1 kg ⇒ 1,000,000 mg

0.5 kg ⇒ x mg

So: $x=\frac{0.5 kgx1,000,000 mg}{1 kg}$

<u><em>x= 500,000 mg</em></u>

Then, you know that each medicinal tablet has a mass of 250 mg, while the mass of all tablets is 500,000 mg. Now that the values are in the same units, to calculate the number of medicinal tablets you must apply the following rule of three: if 1 tablet has a mass of 250 mg, how many tablets have a mass of 500,000 mg?

$number of medicinal tablets=\frac{500,000 mgx1 tablet}{250 mg}$

<u><em>number of medicinal tablets= 2,000</em></u>

Finally, the number of tablets in the bottle is 2,000.

How much force is required to produce a torque of 100 Nm if the force is applied at an angle of 40 at a distance of 25 cm from t

Fudgin [204]

Answer:

Force, F = 622.28 N

Explanation:

It is given that,

Torque, $\tau=100\ N-m$

Angle between force and displacement, $\theta=40^{\circ}$

Distance, d = 25 cm = 0.25 m

We need to find the force required to produce the torque. Torque produced by an object is given by :

$\tau=Fd\sin\theta$

F is force required to produce torque

$F=\dfrac{\tau}{d\sin\theta}\\\\F=\dfrac{100}{0.25\times \sin(40)}\\\\F=622.28\ N$

So, applied force is 622.28 N.

6. The temperature of a mass of tin increases from 24.0 degrees C to 34.0 degrees C when 250 J of thermal energy are added. Calc

irina [24]

Answer:

110 g

Explanation:

q = mCΔT

where q is heat, m is mass, C is specific heat capacity, and ΔT is change in temperature.

Given q = 250 J, C = 0.228 J/g/°C, and ΔT = 10.0 °C:

250 J = m (0.228 J/g/°C) (10.0 °C)

m = 110 g
