The animal's weight is
(mass) x (gravity)
= (0.05 kg) x (9.8 m/s²) = 0.49 newton.
That's the minimum force you can use to pick it up.
That's the force applied by the person to pick up the pig
at a nice gentle constant speed.
Then the net force on the pig is zero. The upward and downward
forces add up to zero, and that's why the animal is moving at a
constant speed, and not accelerating up or down.
This causes the resistance to INCREASE and the current to DECREASE
Answer:
Microwaves are a type of wave that are sandwiched between radio waves and infrared radiation on the electromagnetic spectrum. In the case of microwave ovens, the commonly used wave frequency is roughly 2,450 megahertz.
Answer:
15000000 m
Explanation:
From the question,
Speed (S) = Distance(d)/Time(t)
S = d/t....................... Equation 1
Make d the subject of the equation
d = St..................... Equation 2
Given: S = 50 km/s = 50000 m/s, t = 5 minutes = 5*60 seconds = 300 seconds
Substitute these values into equation 2
d = 50000(300)
d = 15000000 m
Hence the skier travels 15000000 m
Answer:
C) 4.0 m/s²
Explanation:
Given data
- Applied force (F): 120 Newton
- Mass of the object (m): 30 kilograms
- Acceleration of the object (a): to be determined
We can find the acceleration of the object using Newton's second law of motion.
F = m . a
a = F / m = 120 N / 30 kg = 4.0 m/s²
The acceleration of the object is 4.0 m/s².
