Answer:
779.87 N/m²
Explanation:
Pressure = Force (F) / Area (A)
Recall :
Force = ma ; mass * acceleration due to gravity
a = 9.8 m/s² ; mass = 0.4kg
Force, F = 0.4 * 9.8 = 3.92 N
Area = πr² ; r = Radius = 4cm = 4 / 100 = 0.04 m
Area = π0.04² = 0.0050265 m²
Hence,
Pressure = 3.92 / 0.0050265
Pressure = 779.86670 N/m²
Pressure = 779.87 N/m²
Answer:
1.09 km, 3 km
Explanation:
displacement, d = 3.20 km at 20° North of east
A vector quantity has two components one along the x axis and the other is along Y axis. the component along X axis is called the horizontal component and it is due east.
The component along y axis is called vertical component and it is due North.
Displacement due North, dy = 3.20 Sin 20° = 1.09 km
Displacement due east, dx = 3.20 Cos 20° = 3 km
Answer:
1890J
Explanation:
375+45 = 420kg (total mass)
kinetic energy = 1/2 × mass × velocity²
1/2 × 420 × 3² = 1890J
Im sure what is broken down is glucose.
