Answer:
F=G(m1m2)/Rsquare if radius is given 
F=G(m1m2)/dsquare if distance is given
where,
f =gravitational force
G =gravitational constant
m1=mass of one object
m2=mass of another object
d=distance between two object from their center r=radius of earth/planet
 
        
             
        
        
        
Answer:
Alpha particles Ichargeq q = + 2e mass m=6.8*10^ -27 kg) at 17*10^ 4 m/s What magnetic field strength would be required to bend them into a circular path of radiuse c = 0.25m
Explanation:

this is false, they can lift up to 10,000 pounds at a time 
 
        
                    
             
        
        
        
Afor:6000Nm
Explanation: work=force×distance
Work=150×40
Work=6000Nm
 
        
             
        
        
        
Answer:

Explanation:
Temperature of the house, 
Convert to rankine, 
Heat is extracted at 40°F i.e 
Calculate the coefficient of performance of the heat pump, COP

The minimum power required to run the heat pump is given by the formula:
 ...............(*)
...............(*)
Where the heat losses from the house, 
Substituting these values into * above
