Answer: Hi, isolines refer to lines where some quantity maintains constant.

For example, an "istoremal line" is a line where the temperature is constant, an "isobaric line" is a line where the pressure is constant.

Where constant means that, in the two examples i give you, in all the line the temperature or the pressure has the same value.

A thing that you usually can see in a whether map, is that the isolines are "closed" curves. And other thing, maybe more obvious, is that a line cant pass over other line (because this will mean that a point in the space has 2 different values of something).

A record of travel along a straight path is as follows: 1. Start from rest with constant acceleration of 2.24 m/s2 for 10.0 s. 2

valentina_108 [34]

Answer:

1817.448 m

Explanation:

Given:

Initial acceleration = 2.24 m/s²

Time for acceleration = 10 s

From Newton's equation of motion

v = u + at

here v is the final velocity after the acceleration

v = 0 + 2.24 × 10 = 22.4 m/s

thus,

the displacement during acceleration

From Newton's equation of motion

$s_1=ut+\frac{1}{2}at^2$

where,

s is the distance

u is the initial speed = 0 m/s as starting from rest

a is the acceleration

t is the time

on substituting the respective values, we get

$s_1=0\times10+\frac{1}{2}\times2.24\times10^2$

s₁ = 112 m

for case 2

time = 1.25 minute = 1.25 × 60 = 75 seconds

displacement, s₂ = v × t = 22.4 × 75 = 1680 m

for the case 3

acceleration = - 9.86 m/s²

now,

the final velocity for the second case is the initial velocity for this case

thus,

$s_3=22.4\times2.27+\frac{1}{2}(-9.86)\times2.27^2$

s₃ = 50.848 - 25.40 = 25.448 m

hence,

the total displacement = s₁ + s₂ + s₃ = 112 m + 1680 m + 25.448 m

= 1817.448 m

A small 32-kilogram canoe broke free of its dock and is now floating downriver at a speed of 2.5 m/s. What is

marysya [2.9K]

<h3>Answer:</h3>

80 kgm/s

<h3>Explanation:</h3>

<u>We are given;</u>

Mass of the Canoe is 32 kg
Speed of the Canoe is 2.5 m/s

We are required to calculate the momentum of the Canoe?

We need to know that momentum is the product of mass of an object and its speed.

Therefore;

Momentum = Mass × speed

Therefore;

Momentum = 32 kg × 2.5 m/s

= 80 Kgm/s

Thus, the momentum of the Canoe is 80 kgm/s.

Answer:

force F = 1.66 × $10^{-13}$ N

Explanation:

given data

proton and an electron = 865 nm

solution

we get here force that is express as

force F = k q1 q2 ÷ r² ......................1

put here value and we get

force F = 9 × $10^{9}$ × $\frac{1.6\times (10^{-19})^{2}}{865 \times (10^{-9})^{2}}$

force F = 1.66 × $10^{-13}$ N
