Answer:

If you are talking about phones then you can use a camera but if you are talking about a person seeing slow motion I think it's not very possible unless your drunk but in any other way then probably not.

A river flows due east at 1.50 m/s. A boat crosses the river from the south shore to the north shore by maintaining a constant v

monitta

Answer:

$u = 10.11 \ m/s$

$x = 44.996 \ m$

Explanation:

From the question we are told that

The velocity of the river due east is $v = 1.150i \ m /s$

The velocity of the boat due north is $v_1 = 10j \ m/ s$

The width of the river is $d = 300 \ m$

Generally the velocity of the boat relative to the shore

$u = \sqrt{v^2 + v_1^2}$

=> $u = \sqrt{1.50 ^2 + 10^2}$

=> $u = 10.11 \ m/s$

Generally direction of the boat relative to the shore is mathematically represented as

$tan \theta = \frac{v}{v_1}$

=> $\theta = tan^{-1}[ \frac{v}{v_1}]$

=> $\theta = tan^{-1}[ \frac{1.5}{10}]$

=> $\theta = 8.53^o$

Generally the distance covered by the boat in the direction of flow of the river before reaching the north shore is mathematically represented as

$x = d* tan(\theta )$

=> $x = 300 * tan(8.53)$

=> $x = 44.996 \ m$

Your teacher had not exercised since the beginning of distance learning. She decided to exercise by walking in the park. The par

Lesechka [4]

A) 6000 m

B) 0 m

C) 3.33 m/s

D) 0 m/s

Explanation:

In physics, distance is a scalar quantity that represents the total length of the path covered by an object during its motion.

Being a scalar quantity, it has no direction, but only a magnitude (so, a number + its units).

The distance covered by a body can be calculated by adding together all the lengths of all the motion of the body.

In this problem, the teacher walks in the partk, starting at position A, then walking around the park 5 times and returning to the original position.

The park has a rectangular shape 200 m x 400 m, so the perimeter of the park is:

$p=200+400+200+400=1200 m$

The teacher covers the perimeter 5 times, so the total distance she covered is:

$d=5p=5\cdot 1200 =6000 m$

Displacement, instead, is a vector quantity that connects the initial position to the final position of the motion of an object.

Being a vector, it has both a magnitude and a direction, where:

- The magnitude is equal to the length of the vector, so it corresponds to the shortest distance in a straight line between the initial and final position

- The direction goes from the initial position to the final position

In this problem:

- The teacher starts her motion at position A

- The teacher ends her motion at position A

So, the distance between the initial and final position is zero:

$d=x_A -x_A = 0$

And therefore, the displacement is zero.

The average speed of an object is a scalar quantity telling us how fast an object is moving, regardless of its direction of motion.

Being a scalar quantity, it has only a magnitude, and no direction.

The average speed is given by the equation:

$v=\frac{d}{t}$

where

d is the distance covered by the object

t is the time elapsed

In this problem we have:

d = 6000 m is the distance covered by the teacher

t = 30 min = 1800 s is the time elapsed

Therefore, the average speed is:

$v=\frac{6000}{1800}=3.33 m/s$

The average velocity of an object is a vector quantity telling us how fast an object is moving but also its direction of motion.

Being a vector, it has both a magnitude and a direction, where:

- The direction corresponds to the direction of the displacement

- The magnitude is given by the formula:

$v=\frac{d}{t}$

where

d is the displacement of the object

t is the time elapsed

In this problem:

d = 0 is the displacement of the teacher

t = 1800 s is the time elapsed

Therefore, the average velocity is zero:

$v=\frac{0}{1800}=0 m/s$

A positive charge is placed at rest at the center of a region of space in which there is a uniform electric field. (A uniform fi

Harlamova29_29 [7]

Answer:

.D.It will decrease because the charge will move in the direction of the electric field

Explanation:

<em>which there is a uniform electric field. (A uniform field is one whose strength and direction are the same at all points within the region.) What happens to the electric potential energy of the positive charge, after the charge is released from rest in the uniform electric field?A. It will remain constant because the electric field is uniform.B.It will decrease because the charge will move in the opposite direction of the electric field.C.It will remain constant because the charge remains at rest.D.It will decrease because the charge will move in the direction of the electric field.E.It will increase because the charge will move in the direction of the electric field.</em>

solution

The potential energy decreases, converted to kinetic energy

The charge will feel a force in the direction of the electric field (F=Eq) and thus it will accelerate with

a constant acceleration. (Just like releasing an object above the earth's surface - constant acceleration,

at least until it hits something.)

tus te answer will be

.D.It will decrease because the charge will move in the direction of the electric field

Rearranged the equation d=10 v=2.5 for t

eimsori [14]

The time of motion of the object at the given speed and distance is 4 seconds.

<h3>Time of motion of the object</h3>

The time of motion of the object is calculated as follows;

t = d/v

where;

d is distance = 10 m
v is speed = 2.5 m/s
t is time of motion

t = 10/2.5

t = 4 s

Thus, the time of motion of the object at the given speed and distance is 4 seconds.
