Answer:

0.01 ml

Explanation:

Graduated cylinder is used to measurement of volume of liquid.Generally it gives precise result up to 2 digit or up to 3 digit.

Graduated cylinder are of different types .10 mL graduated cylinder measure up to 2 digit while 100 mL graduated cylinder measure up to 1 digit .

So here it is not size of cylinder is not specified so for most precise result the degree of precision of graduated cylinder will be 0.01 mL (up to 2 didgit).

Answer:

Incomplete question: "Each block has a mass of 0.2 kg"

The speed of the two-block system's center of mass just before the blocks collide is 2.9489 m/s

Explanation:

Given data:

θ = angle of the surface = 37°

m = mass of each block = 0.2 kg

v = speed = 0.35 m/s

t = time to collision = 0.5 s

Question: What is the speed of the two-block system's center of mass just before the blocks collide, vf = ?

Change in momentum:

$delta(P)=F*delta(t)$

$P_{f} -P_{i}=F*delta(t)$

$2m(v_{f} -v_{i})=F*delta(t)$

$v_{i} =0.35-0.35=0$

It is neccesary calculate the force:

$F=(m+m)*g*sin\theta$

Here, g = gravity = 9.8 m/s²

$F=(0.2+0.2)*9.8*sin37=2.3591N$

$v_{f} =\frac{F*delta(t)}{2m} =\frac{2.3591*0.5}{2*0.2} =2.9489m/s$

Assume that in interstellar space the distance between two electrons is about 0.8 cm. The electric force between the two electro

SIZIF [17.4K]

Answer:

F = 3.6 x 10⁻²⁴ N

Explanation:

The force of attraction or repulsion between two charges is given by the Coulomb's Law. Coulomb's Law states that:

F = kq₁q₂/r²

where,

F = Electric Force between electrons = ?

k = Coulomb's Constant = 9 x 10⁹ N.m²/C²

q₁ = q₂ = Charge on electron = 1.6 x 10⁻¹⁹ C

r = distance between electrons = 0.8 cm = 0.008 m

Therefore,

F = (9 x 10⁹ N.m²/C²)(1.6 x 10⁻¹⁹ C)(1.6 x 10⁻¹⁹ C)/(0.008 m)²

an airplane flies for 4 hours with a constant speed of 696 km/h and then for another 35 minutes with a constant sppeed of 936 km

Nastasia [14]

Answer:

Total distance covered by airplane is 3330 km

Explanation:

Distance covered in speed of v= 696 km /hr for t = 4 hours is

$x_{1}=v \times t\\x_{1}=696 \times 4\\x_{1}=2784 km$

Convert given speed in km/min, then distance covered in 35 minutes at speed of 936 km/hr is

$x_{2}=\frac{936}{60} \times 35\\x_{2}==546 km$

Total distance covered by airplane is

$x = x_{1}+x_{2}\\x =2784 +546\\x=3330 km$

Total distance covered by airplane is 3330 km
