Answer:
1700 W
Explanation:
Power = work / time
Power = force × distance / time
Power = force × velocity
P = (35 kg) (9.8 m/s²) (5 m/s)
P = 1700 W
The triarchic theory of intelligence was formulated by Robert J. Sternberg, a prominent figure in the research of human intelligence. The theory by itself was groundbreaking in that it was among the first to go against the psychometric approach to intelligence and take a more cognitive approach
Answer:
In physics, mass–energy equivalence is the principle that anything having mass has an equivalent amount of energy and vice ve
Answer:
force exert horizontally is 1 N
Explanation:
given data
bar length = 3.7 m
mass = 4.5 kg
rope length = 6.7 m
to find out
force exert horizontally
solution
we know here bar length and rope length that make angle θ
so here cos θ = (3.7/6.7)
so equating the torque here to find force in horizontal direction is
Fx = T cos θ .........1
and in vertical direction
Tsinθ + N = mg .............2
so here
we consider equilibrium condition
so
Fx = 0
T cos θ = 0
T 3.7 / 6.7 = 0
T = 6.7/3.7
T = 1.81
so from equation 1
Fx = T cosθ
Fx = 1.81 ( 3.7/6.7)
Fx = 1 N
so force exert horizontally is 1 N
Children with low self efficacy will take a longer time to achieve their targets whereas those with high self effficacy will be more likely to find success easily
