The formula of net Force is:
F = ma
where m is the mass of the object
a is the acceleration of the object
so if we triple the net force applied to the object:
3F = ma
a = 3F / m
so the acceleration will also be tripled. because from the equation, the force is directly proportional to the acceleration
A pulsar has the strongest magnetic field
Answer:
A)Qa=80 J
B)Qr= 100 J
Explanation:
Given that
W= 20 J
COP = 4
Heat rejected from cold reservoir = Qa
Heat exhausted to hot reservoir = Qr
The COP of refrigerator is given as
Qa= 4 x 20 J
Qa=80 J
By using first law of refrigerator
Qr= Qa + W
Qr= 80 + 20 J
Qr= 100 J
A)Qa=80 J
B)Qr= 100 J
Diagram A is the correct diagram
The x and y components of the vector is 31.59 m and 29.46 m respectively.
<h3>
X component of the vector</h3>
The x component is calculated as follows;
v(x) = v cos(43)
v(x) = 43.2 m x cos(43) = 31.59 m
<h3>
Y component of the vector</h3>
The y component is calculated as follows;
v(y) = v sin(43)
v(y) = 43.2 m x sin(43) = 29.46 m
Thus, the x and y components of the vector is 31.59 m and 29.46 m respectively.
