Answer:
A, D, E
Explanation:
The force of Earth's gravitational pull is equal to the mass of the object times the acceleration due to gravity:
W = mg
The greater the mass, the greater the pull.  A truck, bicycle, and camel all have greater mass than a baseball.
 
        
             
        
        
        
Answer:
The driver's average velocity is 82.35 km/h.
Explanation:
Given:
The motion of the driver can be divided into 3 parts:
i. Displacement of the driver in 1.5 hours = 135 km
ii. Rest for 45 minutes.
iii. Displacement in next 2 hours = 215 km
The direction of motion remains same (east).
Now, total displacement of the driver is,  km.
 km.
Rest time is 45 minutes. Converting it to hours, we need to use the conversion factor  hour.
 hour.
So, 45 minutes in hours is equal to  hours.
 hours.
Now, total time taken for the complete journey is, 
Average velocity is given as:

Therefore, the driver's average velocity is 82.35 km/h
 
        
             
        
        
        
The magnitude of acceleration is (change in speed) / (time for the change).
Change in speed = (speed at the end) - (speed at the beginning) = 
                                   (16 m/s)  -  (0)  =  16 m/s .
Time for the change  =  4 s .
Magnitude of acceleration = (16 m/s) / (4 s) = 4 m/s per sec = 4 m/s² .
        
                    
             
        
        
        
Answer:
The correct option is;
Amplitude
Explanation:
When transmitting picture signals over the air by broadcasting stations, the signals are shifted into high frequency channels of Very High Frequency (VHF) or Ultra High Frequency (UHF) carrier currents and imposing the the television signal by changing the amplitude of the high frequency carrier current to match the transmitted television signal waveform shape
