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

what is one effective way to calibrate a thermometer
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°FTo learn more, visit the link below:

write the energy conversion when a moving car braking to stop completely
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.

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.
