What is the magnitude of your total displacement if you have traveled due west with a speed of 23 m/s for 135 s , then due south

at 12 m/s for 295 s ?
Physics

Kamila [148]3 years ago

Answer:

4708.78 m

Explanation:

Applying,

d = vt................ Equation 1

Where d = displacement, v = velocity, t = time

dispalcement due west

Given: v = 23 m/s, t = 135 s

Therefore,

d = 23(135)

d = 3105 m due west.

For south

Given: v = 12 m/s, t = 295 s

Therefore,

d = 12(295)

d = 3540 m

Note: The entire journey forms a right angle triangle

Total displacement = √(3105²+3540²)

Total displacement = √(9641025+12531600)

Total displacement = √(22172625)

Total displacement = 4708.78 m

A 5.6 MeV (kinetic energy) proton enters a 0.39 T field, in a plane perpendicular to the field. What is the radius of its path?
Kisachek [45]

Answer:

the radius of the protons path is r = 0.85 m.

Explanation:

the force due to magnetic fields lead to the cetripetal force, such that:

F = q×v×B = m×(v^2)/r

         q×B = m×v/r

then:

r = m×v/q×B

r = p/q×B

then, the kinetic energy of the proton:

K = 1/2×m×v^2 = p^2/(2×m)

q×B = \sqrt{2×m×K}/r

    r =  \sqrt{2×m×K}/(q×B)

      =  \sqrt{2×(1.67×10^-27)×(5.3×1.60×10^-13)}/(1.60×10^-19×0.39)

      = 0.85 m

At Alpha Centauri's surface, the gravitational force between Alpha Centauri and a 2 kg mass of hot gas has a magnitude of 618.2
sergeinik [125]

Answer:

6.86 * 10^8 m

Explanation:

Parameters given:

Mass of hot gas, m = 2 kg

Gravitational Force, F = 618.2 N

Mass of Alpha Centauri, M = 2.178 * 10^30 kg

The gravitational force between two masses (the hot gas and Alpha Centauri) , m and M, at a distance, r, given as:

F = (G*M*m) / r²

Where G = gravitational constant

Therefore,

618.2 = (6.67 * 10^(-11) * 2.178 * 10^30 * 2) / r²

=> r² = (6.67 * 10^(-11) * 2.178 * 10^30 * 2) / 618.2

r² = 4.699 * 10^17 m²

=> r = 6.86 * 10^8 m

We are told that the hot gas is on the surface of Alpha Centauri, hence, the distance between both their centers is the radius of Alpha Centauri.

The mean radius of Alpha Centauri is 6.86 * 10^8 m.

The cheetah, the fastest of land animals, can run a distance of 274 m in 8.65 s at its top speed. What is the cheetahs tips spee
ycow [4]

Answer:

Top speed is 31.68 m/s

Explanation:

Speed of a body is the distance traveled by the body in unit time.

Speed is generally expressed in meter per second or kilometer per hour.

Here, the cheetah travels a distance of 274 m in 8.65 s.

Therefore, speed of cheetah is the distance traveled by it in one second.

For 8.65 s, distance traveled is 274 m

For 1 s, distance traveled will be \frac{274}{8.65} meters per second. This value is called speed.

So, speed is given as the ratio of the distance traveled to that of the time taken.

∴ Top speed of cheetah is given as:

v_{max}=\frac{274}{8.65}=31.68 \textrm{ m/s}

Here, v_{max} is the top speed of cheetah.

In Hooke's law, Fspring=kΔx , what does the Fspring stand for?
Mrrafil [7]

Answer:

The amount of force acting on the spring.

Explanation:

Here, Fspring= kΔx  is a equation denoting the amount of force acting on the spring.

where, k = spring constant.

           Δx= change in the length of the spring.

so, for every Δx change in spring length, kΔx force acts on the spring.
