Explanation:

This is because the loyalists did not agree with fighting back against Britain and wanted to remain a part of Britain, while the other answers show examples of people who wanted to break away from or rebel against Britain

Answer:

1)So, the mass(m) of the tv is 75kg and the scale(weight)=825 N therefore you devide the weight by the mass which is equal to 11m/s^2

2)First things first you need to know the gravitational force here on earth which is 9.8(approximately 10) I will sove for 9.8 and 10 so you can choose

the fish has a mass of 2.4kg and the gravity= 9.8 so the weight is equal to the mass*gravity= 23.52

now if you use 10 as the gravity= 2.4*10= 24

3) here the weight is 250N and gravity is 9.8(10) so we just devide the weight by the gravity= 250/9.8= 25.51

                         250/10= 25( if gravity is 10)

Answer:

Explanation:

12.since W=mg where m is mass and g which is accelaration due to gravity,

  g=825N/75kg

  g=11 m/s^2

13.W= 2.4kg * 9.81m/s^2

      =23.544kg m/s^2=23.544N

14.m=250N/9.81ms^-2

       =25.48kg

Answer:

It is launched with a speed of 11 m/s.

Explanation:

5. 35 - (-20) = 55

6. [tex]v_{av}=\frac{\Delta s}{\Delta t}=\frac{20-(-20)}{6-0} =\frac{40}{6} =6.67[/tex]

7. D and G

8. A, C, and E

9.

At t = 19,

[tex]s=\frac{s_{final}-s_{initial}}{t_{final}-t_{initial}}(t_1-t_{initial})+s_{initial}=\frac{40-(-20)}{23-18}(19-18)-20=12-20= -8[/tex]

At t = 27,

[tex]s=\frac{s_{final}-s_{initial}}{t_{final}-t_{initial}}(t_1-t_{initial})+s_{initial}=\frac{0-40}{29-26}(27-26)+40=\frac{-40}{3}+40=26.67[/tex]

Therefore, displacement between t = 19 and t = 27 is:

26.67 - (-8) = 34.67

The time required to charge the 64 kwh battery from 0 to full is 45.7 hours.

A level 1 120 V charger supplies a power of 1.4 kW at 20 A.

Since we need to charge a 64 kwh battery with a level 1 120 V charger, the total energy required by the battery is E = 64 kwh.

Since the power rating from the charger is P = 1.4 kW, we know that

energy, E = power, P × time

So, time = energy/power

So, the time required to charge the 64 kwh battery from 0 to full is

time = 64 kwh/1.4 kW

= 45.71 hours

≅ 45.7 hours

So, the time required to charge the 64 kwh battery from 0 to full is 45.7 hours.

Answer:

Friction braking is the most commonly used braking method in modern vehicles. It involves the conversion of kinetic energy to thermal energy by applying friction to the moving parts of a system. The friction force resists motion and in turn generates heat, eventually bringing the velocity to zero.

Answer

both earthquakes and tsunamis have waves  

Explanation:

Tsunamis are caused by earthquakes, underwater land slides, volcanic eruptions, and land sloping into the ocean. An earthquake is rapid shaking of the earths surface. It's no wonder earthquakes cause mass destruction, because they occur when two plates collide. Also earthquakes occur more often than tsunamis do.

The uniform movement allows finding the results for the helicopter displacement during the 10 s is: 700 m

Kinematics studies the motion of bodies, finding relationships between the position, velocity and acceleration of the body, in the special case that the acceleration is zero, it is called uniform motion and is described by the equation

          [tex]v = \frac{\Delta s}{t}[/tex]

Where v is the average velocity, Ds is the displacement and t is the time

          Δs = v t

They indicate that the average speed is 70 m / s and the travel time is t=10.0s

Let's calculate

          Δs = 70 10.0

          Δs = 700 m / s

In conclusion using the uniform movement we can find the results for the helicopter displacement is: 700 m

The magnitude of the helicopter's displacement is 700 meters.

Given the following data:

To find the magnitude of the helicopter's displacement:

Velocity can be defined as the rate of change in displacement (distance) with time.

Also, velocity is a vector quantity and as a result of this, it has both magnitude and direction.

Mathematically, velocity is given by the formula;

[tex]Velocity = \frac{displacement}{time}[/tex]

Making displacement the subject of formula, we have:

[tex]Displacement = velocity[/tex] × [tex]time[/tex]

[tex]Displacement = 70[/tex] × [tex]10[/tex]

Displacement = 700 meters.

Therefore, the magnitude of the helicopter's displacement is 700 meters.
