Pleaseee helppp I need help I don’t know how to do this

Answers

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

helicopter flies an average velocity of 70 m/s2 for 10.0 seconds. What ios ther magnitude of the helicopter's displacement? answer should have 3 significant figures

Answers

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

Learn more here: brainly.com/question/14355103

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

Given the following data:

Velocity = 70 m/sTime = 10 seconds.

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.

how long does it take to charge a 64-kwh battery from 0 to full using a level 1, 120v charger?

Answers

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.

Calibration can be defined as the way an instrument is adjusted such that the measurement the instrument gives after calibration is precise and accurate.

One effective way to calibrate a thermometer is the use of ice water.

A thermometer can be defined as the instrument used to measure the temperature of a person or a substance.

A thermometer should be calibrated regularly in order to maintain a high level of precision and accuracy.

One of the effective ways to calibrate a thermometer is through the use of ice water.

The steps to calibrate a thermometer are given below:

Get a bowl, place some ice cubes in it and add additional cold water to it.    Place thermometer probe between 2 -3 inches deep in the water. For accurate calibration, make sure you prevent the thermometer from touching the sides of the glass.  Stir and wait for a few seconds. The thermometer should be properly calibrated when you read the measurements and it says 32°F
