Answer:
380000 km
Explanation:
The number is 380000
From the right
The first digit is the ones place
The second digit is the tens place
The third digit is the hundreds place
The fourth digit is the thousands place
The fifth digit is the ten thousands place
The sixth digit is the hundred thousands place
While reading a number we read the first digit on the left and add which place it is at.
Then the next digit as well as the place it is at.
Here the 3 is at the hundred thousands place. So, we say three hundred.
Then we read the next digit which is 8 and is at the ten thousands place.
So, we say three hundred and eighty thousand
It’s B. Require a small force over a long distance
Answer:
x = 2.37 cm
Explanation:
given,
density of oil = 923 kg/m³
height of the block = 4.81 cm
density of the block = 961 Kg/m³
density of water = 1000 Kg/m³
Let x be the depth of the block in the water.
now,
Weight of block will be acting downward.
Buoyancy force will be acting on the block because of the oil and water.
At equilibrium position both weight and the buoyant force will balance.
x = 0.0237 m
x = 2.37 cm
Hence, the block is 2.37 cm in the water.
C. you need to double your speed.
since there is gravity and the more mass the more gravity pulls it to the core of the earth; cars are heavy.
Answer:
Mass is the measure of an object's matter (what it's made up of). The greater an object's mass, the greater its gravitational force. The earth has a strong attracting force for objects with smaller mass (including the moon), and the sun has an attracting force on the earth and other planets in our solar system.
