Answer:
d. 1.69 * 10^6 N
Explanation:
Pressure is defined as force divided by area.
Answer:
C. 69.0 kJ
Explanation:
Step 1: Given data
Mass of the horse (m): 500 kg
Distance traveled by the horse (d): 2000 m
Time elapsed (t): 120 s
Step 2: Calculate the speed of the horse (v)
The speed of the horse is equal to the distance traveled divided by the time elapsed.
v = d/t
v = 2000 m/120 s
v = 16.6 m/s
Step 3: Calculate the kinetic energy (K) of the horse
We will use the following expression.
K = 1/2 × m × v²
K = 1/2 × 500 kg × (16.6 m/s)²
K = 6.90 × 10⁴ J
Step 4: Convert "K" to kJ
We will use the conversion factor 1 kJ = 1000 J.
6.90 × 10⁴ J × (1 kJ/1000 J) = 69.0 kJ
Answer:
Acceleration(a)=3m/s^2
Time(t)=1min[1min=60s]
=1×60
=60s
Initial velocity(u)=0m/s
Velocity(v)=?
We know that,
Acceleration=v-u/t
Or,3m/s^2=v-0/60
Or,3×60=v-0
Or,v=180m/s
So,the velocity is 180m/s.
Hope,it will helpyouu!
Sedimentary Rocks are made from previously existing rock.
The first law states that “objects at rest and objects in motion remain in motion in a straight line unless acted upon by an unbalanced force”. Keeping the ice smooth will make sure there is not friction, friction would slow the puck down
