an object is thrown horizontally off a cliff with an initial velocity of 5.0 meters per second. the object strikes the ground 3.

Olegator [25]

You know that the formula for finding horizontal displacement is;

s=uₓt
s=(5 m/s)(3s)
s=15 m

Therefore, the ball travelled 15 m.

Hope I helped :)

Which statement best explains the relationship between the electric force between two charged objects and the distance between t

spin [16.1K]

Unfortunately, the given statements are missing from the problem. However, we can still determine the relationship between the electric force between two objects and the distance between them. The formula for the electric force is given below:

F = (k*Q1*Q2)/d^2

k is a constant, while Q1 and Q2 are the respective charges of the objects. F is force, while d is distance.

As seen in the formula, we can see that the electric force F is inversely proportional to the square of the distance between the two objects.

The fastest propeller-driven aircraft is the Russian TU-95/142, which canreach a maximum speed of 925 km/h. For this speed, calc

valentinak56 [21]

Answer:

The resultant displacement of plane = 1310.76 Km

Explanation:

Given that,

Speed of the plane = 925 Km/h

Therefore, in 1 hour plane travels 925 Km

From figure,

Displacement if it travels east for 1.5 h, AB = 1387.5 Km

Displacement if it travels north-west for 2 h, BC = 1850 Km

Angle formed between two displacement = 135°

The resultant displacement is given by the relation

AC² = AB² + BC² + 2 AB BC Cos θ

Substituting the values in the equations,

AC² = 1387.5² + 1850² + 2 x 1387.5 x 1850 x Cos 135°

= 1718095

AC = 1310.76

Therefore, the resultant displacement of plane is 1310.76 Km

A single-turn circular loop of radius 14 cm is to produce a field at its center that will just cancel the earth's magnetic field

Olin [163]

Answer:

49 A

Explanation:

We are given that

Number of turns,N=1

Radius,r=14 cm= $\frac{14}{100}=0.14 m$

1 m=100 cm

Magnetic field,B=0.7 G= $0.7\times 10^{-4} T$

$1G=10^{-4} T$

$\mu_0=4\pi\times 10^{-7} Tm/A$

We know that magnetic field

$B=\frac{\mu_0IN}{2\pi r}$

Substitute the values

$0.7\times 10^{-4}=\frac{4\pi\times 10^{-7}\times 1\times I}{2\pi\times 0.14}$

$I=\frac{0.7\times 10^{-4}\times 2\pi\times 0.14}{4\pi\times 10^{-7}\times 1}$

$I=49A$
